General :: Message In Terminal After Redirecting Output And Build Completes?
Oct 9, 2010
I'm not sure about the following behavior so thought I would put it out to see if there is an error I need to resolve, or simply a process that I need explained.I'm also not sure if this is an Ubuntu issue, a Linux issue, or other... but here goes.I ran my "make build" in two different ways; one with just "make build" and one with "make build > output" (so I could review the full script).With just "make build" the process finished and returned to the command prompt.
With "make build > output", after the process had finished (script in output document identical to what was in the terminal with "make build") a new set of data was displayed in the terminal (see below).With the other examples of using "make build > output" the times it would parse something back to the terminal window was when there was an error. As I fixed the errors these breaks back to the terminal window would stop. So I'm wondering if this indicates a new error, but because the "make build" now completes successfully (at least it appears to), I'm wondering if this data in the terminal window is just a behavior related to redirecting the output script using the ">" process and something to do with returning to the terminal once a process completes
I have a script that uses cp to copy data from A to B. There are some troublesome files that are constantly in use and read "Permission denied" or "Text file busy" but I'm not worried about these. Therefore my copy process always contains output.The script runs through cron and the output (automatically) goes to /var/mail/user. I tried setting it up to send me an email and it comes through, but it's completely blank. The email in /var/mail/ contains the full output.
Here is my command: 0 18 * * * /home/backup.sh | mail -s "Backup completed" jsteel@...com (The script simply contains many "cp -r /mnt/location/a /mnt/location/b")
I have seen a post where someone was explaining the virtuality of stdout and stderr and that it can be redirected with e.g. 2>file.txt but this apparently is not working for me! I have a CUPS filter with fprintf(stderr,...)
This seems so simple when doing it from command line but I'm not able to accomplish it inside a script. I am trying to put output of following command into a text file:
CMD= mysql -uroot -psecret -e 'SHOW SLAVE STATUS G;' FIL=~/replication-`date +%F`.txt MAILTEXT=~/mailtext.txt touch $FIL $CMD > $FIL
Where FIL is a variable that contains path of the file to which to output command. I am running this command in a shell script from where I want to email contents of $FIL as attachment using mutt. But I am always getting 0 byte file. Also if I examine in directory the file is of 0 byte length.
So I have a DAC/Headphone Amplifier which plugs in through USB. Through the system settings I'm able to set it as the preferred audio output option. This makes all the windows manager sounds come through the headphones, but all the applications still come through the laptop speakers; i guess they are completely independent of the system settings. I have to set each application's output preferences separately, and some software (like Firefox) doesn't have any output preferences. So is there a way toirect the audio output of all applications to all come through the USB DAC
I want to run gsettings list-schemas (which return a list of about 100 names separated by spaces)and somehow direct each name one at a time as the input to this command:gsettings list-recursivelyI've tried it with awk, and standard | piping and also as a string variable strvar=$(gsettings list-schemas) and using the $strvar as the input butam missing something in between I'm sure like for - while or proper syntax of awk etc
When I run 'sendmail -bv', it sends the mail delivery status report as a mail to the root. Is there a way I can redirect this to the console instead of sending as a mail. requirement is to programatically find the mail host of the recipient for which I thought of using this 'sendmail -bv' command. Is there any other better way to find mail host of the recipient
Today I tried to use padevchooser on Natty to send my laptop audio to my home media machine (which has the good speakers) using the "default server" option. Turns out padevchooser doesn't work on Unity and the threads I have seen say it is deprecated for other gui tools,
So what is the easy gui way to switch from my local pulse server to another one on my LAN, without using padevchooser, or switching off Unity? Or is this a regression?
I've got a C program that I've added some 'printf' statements to monitor a couple of variables. When I run this program manually or from a script, the output is displayed on screen. However, I need to change various variables in the 'test.c' file, run 'make clean' and 'make' a few hundred thousand times. I'm using a script to read the variables in and then using sed to do in-place edits of the file. Unfortunately, with this amount of iteration, it is getting rather tired!
Anyway, I've created a script that is working as long I respond to prompts. I've tried the following to no avail: Code: /path/to/script > /tmp/output /path/to/script > /tmp/output 2>&1 /path/to/script | tee (no output even after adding the -a option) In my C program, I have the following 'printf' statement: Code: printf ("variable1: $s variable2: $s",var1,var2); What am I missing? I've worked with redirection before and it's always worked out fine, but this one plain stumps!
I am developing a application. In this I fork() 3 childs(lets say child1 , child2, child3) . The parent is now waiting for some input from keyboard.Child3 is continously getting data from child1 and child2 using pipe which it then will print using printf.Now as the parent is waiting for input from user through keyboard while child3 is continously printing the data. I want to do it in different terminals.Can you please guide me how to proceed ahead so that on one terminal , the parent waits for input fromser while on other terminal child3 prints data.
hello I tried to find a good subject but it was the best of mine, anyway I'll explain it here. some time I do some thing like installing a new application in Linux terminal of my office PC but it take a long time and I have to go home during its installation or configuration process that it is not good to cancel it.My current solution is abandoning the process until next day. I wanted to know is there any way to redirect an input and out put of a terminal to another one, if it works I can continue my abandoned process by ssh to my Linux office PC and redirect that terminal to my new remote sshed terminal from my home.
I'm new to LinuxQuestions and this is my first post. I'm trying to build rrdtool to install Cacti and encountered the following problem: 'make' step returns an error messages:
Code: ./.libs/librrd.so: undefined reference to `xmlTextReaderGetParserLineNumber' collect2: ld returned 1 exit status What I have doneDownload and build the latest version of pkg-config, glib, pixman, cairo, pango, atk, gtk+ from official sites. Download rrdtool source Set PKG_CONFIG_PATH correctly
[Code]...
There is actually another problem with the computer which is "The Nautilus application has quit unexpectedly" everytime I open File Browser application or right-click>Properties a file/directory. This happen only after installing cairo and pango and I don't know how to revert to old version. Since there are a lot of log files so I'm very confused. Can someone give me a direction on how to resolve this?
When iwconfig is redirected thus Code: iwconfig >> wireless.txt things like Code: eth0 - Has no wireles extension are still outputted to the terminal (stdout)
I'd like to instruct bash to use a special method to perform completion on certain directory names. For example, bash would call a program of mine to perform completion if a path starts with "$$", and perform completion normally otherwise. Is this at all possible? How would you implement it? The goal is to allow autojump to complete paths for all commands when the user starts them with a certain prefix. So for example when copying a file from a far directory, you could type: cp $$patern + <Tab>
and autojump would complete cp /home/user/CompliCatedDireCTOry/long/path/bla/bla and you would just have to add where you want to put the file. Of course I can use ott's comment to add it to a few specific commands
if we type a command such as "locate somefilename" in the terminal we will get all the paths to the file name as output. If i want to copy only one line from that output how do i do that without using mouse?i need terminal short cut to copy one line
OS is CentOS 5.5, and GNOME terminal emulator (v2.16.0). However I regard the question is not related with OS/Gnome version level. My question is whether if color setting is available or not for the text character outputted by kernel (or shell, i.e. Bash). Normally we can specify/modify text character color (and background color) with property setting on the terminal. However, it only takes affect to the text for inputting character, not for outputted character by kernel/shell. For example, when we type a shell command "ls -al <cr>", the text appears with the color along with the terminal property.
Meanwhile, the text message displayed on the console (output message against "ls -al" command), in this case it must be file and/or directory names, will appear with some preset color which we've not preliminarily set. In my case, I set Text color with "White", Background color with "Black". Then I expect the text output message color displayed by kernel/shell would be some brighter color. But the color is "blue" which does not look better brightness against "Black" background. For this situation what I'd like to know is how to set/specify the color outputted by the kernel/shell (or whether or not it is possible to set manually).
Is there a way to get colored output when using tab completion in a terminal? My colors are fine everywhere else so I know that I've enabled a color terminal successfully. Using bash in Ubuntu (10.10).
I want local programmatic access to ssh output in Mac Terminal. First, I tried redirecting the output of each command to a file. The file was perfect, but of course it was on the remote server, and an sftp for each command output seemed a little.. Next, I tried to Applescript Terminal, but it only gives access to the currently visible text in a tab (i.e. if half the output has already scrolled out of sight, it doesn't get returned - useless).
Last, I tried piping ssh to tee (e.g. ssh user@host | tee output.txt). This almost worked. I have the output in a local file, but there are a lot of unwanted characters mixed in. For example, every time I hit backspace, there's a ^H in the file. There's also text like "[0m[K" which is harder to get rid of.
I often have issues starting my window manager--xfce. My computer misbehaves in one of 3 ways, one of which is to fail to open X, but generate several screens of info. I want to paste that info to this site, but since I'm in the shell, not the terminal (please correct my vocabulary if it's wrong here), I don't know how to copy and paste the output, since right-clicking doesn't give me a menu. Even if I could copy I'm not sure the information would be accessible in X. Are there any other options?
i have a process launch by another app, i want to see the output (that is in console) in a terminal (gnome-terminal or tty); how can i capture de standart I/O from a process. my process (aria2) is launch by firefox and the output of ps is like:
...is running but i cant see the output (download state), how can i capture or redirect standart I/O to my terminal to get something like the output of:
Using a default terminal and bash, there is no functionality to search the standard output of commands.
One can gain such functionality using other tools, like emacs shell or screen, but I am wondering why such a useful feature is missing, I do remember a simple C-F used to work in terminals.
Is there a way to make the Gnome terminal app support output search? or is there a better terminal app that support searching output natively?
I know how to redirect the output of a terminal to a file. For example, if I want to list all the files in ~/Documents and output to a file called test.txt, I would do this: ls ~/Documents > test.txt The question is, can I copy the output to test.txt AFTER I have carried out the command? This would mean that I wouldn't have to know in advance whether I want to copy the output to file. I want to do something like this: ls ~/Documents Then this: <bash command for copying standard output to test.txt>
