General :: Copy Previous Output From Bash Terminal To File?
Oct 26, 2010
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>
Is it possible to use the keyboard in order to select some text in the terminal windows that is not in the currently edited line? (for example, in order to copy part of previous command output).
For example, I run a program called "luck" and it outputs a sentence like "good luck". Then "./luck -> logfile" will save the output content to logfile.But when I run another program called "hello" and it outputs a sentence lie " Hello world".Then "./hello-> logfile" will save the output content to logfile and wipe the previous contents.Is is possible to keep both sentences in the logfile? Just like
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
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?
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).
!<number> to execute the Nth command(use history to see the list). Or you can use
Code:
cd !-2:1
to cd into the value in the first field that was executed 2 commands ago Anyhow, say I run a command and the output is a path. Any way to cd and then some variable where OUTPUT of the previous command was stored? A variable that always stores the OUTPUT of the last command.
I am using openSUSE 10.3.When I install software from tarball then to record time required I send output of date to beg.txt(when installation begins) and end.txt (when installation finishes).How can I append output of date to a file so I don't need two files?
I've shell bash file script and I want to save the output into a txt file.I Know ./bash.sh > output.txt will save the result into a file but i want to add something into a bash file and then when the bash file process completed, it save the result into a file and I don't want that overwrite the output into the old file, I want each time i run it, it save the result into a new file.
I have got a script with an outer and inner loop. The inner loop issues loads of echo's which need to be redirected to a log file determined by the outer loop. The obvious solution is to redirect every echo to >$LOG and set LOG in the outer loop.
Code:
for f in $FILES ; do LOG=<logfile> for l in $LINES ; do
[code]....
it is possible to map stdout to $LOG in the outer loop without having to redirect every subsequent individual command output?
I would like to capture all output spewed to a terminal session including processes that are terminated that were invoked from a script running in a terminal window. this is beyond capturing just stderr and stdout . for example
{ ./script } 2> stderr.cap 1>stdout.cap
if script is terminated (including because of memory violations) I get spewed output to the terminal I would like to capture that spewing to a file automatically or to a bit bucket /dev/null Is there another filehandle which can be redirected to do this? If so how or is there another way???
I sometimes stick my neck out and provide somewhat detailed, and often risky, "Mr-fix-it" remedies for boot problems. Now, I know it's possible to amend each command with "whatever_command > whatever.txt" in which case it'll place the command output in a file in /home.
But if you're directing someone to run a lot of commands as I did here is it possible to save the output of all commands to a .txt file without amending each command?
Or is it already saved somewhere that I'm not yet aware of? I wouldn't be surprised if the latter were true, I just haven't yet found it
I have a directory and sub-directories (4 or 5 depths). There are several type with extension in them (*.mp3, *.wma, *.jpg, etc). I would like to copy the whole directory to another location recursively but only *.mp3 files.
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 need this script but I don't know how to do it I have one folder with several folders inside.On each folder a have one MKV or AVI file inside...What I need is a script to change the "modification date" of each folder to the "modification date" of each MKV or AVI that the folder has inside.
I want to use the output of a previous command as a parameter to another command. For example: to know where "nice" is stored i typed: which nice output: /usr/bin/nice now the second command i typed is: ls -l /usr/bin/nice Is there a way to have a single command like: ls -l which nice ?
I'm trying to create an iso file in a terminal with the following command: $cat /dev/sr0 > nameofdisk.iso I get the following error cat: /dev/sr0: Input/output error I already checked and my optical drive is indeed /dev/sr0. I've hunted google a few hours trying to figure it out. Does anyone know why I'd be getting this error?
Is there one command that will let me record an entire terminal session (with any possible errors) to a text file while also seeing all output on screen too? I know it can be done for individual commands, but I'm looking to do this for an entire session where the individual commands will be normal (i.e., not piped into tee, etc.). It would be even better if the command prompt is captured too. The obvious utility of this makes me think someone surely has come up with a solution long ago (probably in the 60's).(I'm sure it goes without saying, but subsequent output in that session should be appended to the file. The file should contain the full history, with all output and errors, of the session.)
I am working on a script that allows me to convert an IP address to a country name. I have 2 files. One that has text like: PORT.80 TCP SRC=x.x.x.x and the other is x.x.x.x United States. How can I combine these files so that the file output is PORT.80 TCP SRC=x.x.x.x United States?
For example, if I type ':pwd' to get the current working directory, I can select the text in gvim but I can't figure out how to copy it to the clipboard. If I try the same in console vim, I can't even select it with the mouse. I would like this to work with all vim commands, such as set guifont to copy the guifont=Consolas:h10:cANSI output.
I have installed fail2ban and it is working great. It is monitoring the auth.log and it's own log. Now here is my question... Every week, my log files rotate, which is just fine for the most part. But this also rotates the fail2ban log and removes any chance of catching a repeated IP from Sunday to Monday. Is it possible to copy a portion of the previous log to the new log?Here is my scenario of what I would like to accomplish, but I am a novice here so please be specific..
logrotate does its job as expected... then a script writes a portion of the previous log to the new log then appends a word/number after that portion (we call this log.1)...next time the log rotates (creating log.2), I want to take the portion of log.1 after the word/number and append it to log.2 along with another word/numberThis will always ensure there is at least 1 week backlog in the logs for fail2ban to track. I don't want to just change the frequency of the log-roll because it doesn't solve the issue of tracking across the log roll
is it possible to log the command output's history that are previously printed messages in the terminal to a file? that is the first command output when i first opened terminal through the last command.
How to copy a Read-Only file in Linux and make the copy writable with a single cp command in Linux (Ubuntu 10.04)? The --no-preserve and --preserve seemed to be good candidates, except that they should "and" the mode flags, while what I am looking for is something that will "or" them (add +w mode).
More details: I have to import a repository from GIT to Perforce. I want that all Perforce depot files are Read-Only (that is how Perforce was designed), while all other files that were derived/copied from depot files are writable. Currently if a Makefile tries to copy a Read-Only file then the derived file will also be Read-only. This leads to build-errors when cp tries to overwrite Read-Only file second time. Of course the --force is a workaround here but then the derived file is also Read-Only. Also I do not want to mess with "chmod" after each "cp" command - I will do that only as the last resort.
Just wondering if anyone would be kind enough to point me to a link for the adobe flash plugin version previous to version 10.1 for i386. I don't have anything in /var/cache/yum/i386/12/adobe-linux-i386/packages/ because I think I cleared yum's cache. I'm experiencing major regressions with flash 10.1, stuttering videos and some videos no longer play. Version 10.1 is a major disaster for adobe. It really is appalling for an update. Also, if anyone else is experiencing flash version 10.1 issues, please share and if anyone is considering upgrading to it, my advice is keep the old one handy, you will likely need it.
I just set up apache on my PC and I cant change the permissions by right clicking because "I'm not the owner" and instead of using the chmod command on every file that I would like to edit I would just like to write a script on a text file, save it to my desktop so all I have to do is double click on it and boom I can edit all my files, etc.
