Ubuntu :: Capturing ALL Output From Terminal To File?
Apr 17, 2010
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 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've made a simple php wrapper around scp. It works fine, but unlike when I run the scp command straight from the console, there is no output returned. I've tried using passthru(), exec(), system() and shell_exec(), all to no avail. I'm redirecting stderr to stdout already.
Will scp the files correctly to the server, but doesn't print any output - $result is just an empty array. I'd like to see the output so I can visually confirm that the files have been transferred correctly.
then luvcview should capture the video to the .avi file. However, when I try it, no output file is created. Grabbing a raw stream or raw frames works fine, but not the creation of AVI files. Am I missing something?
I run a 3rd party command line utility and it works fine, but sometimes it says "Error blah blah blah... Connection timed out"
I want to script this utility, but I need to not execute the commands in the script if it gives me that connection timeout error.
bash code to capture that response from the utility? Something along the lines of:
Quote:
#!/bin/bash 3rdpartyutil > /tmp/temp.txt if [ ! -f /tmp/temp.txt]; then echo no error, run whatever you need to man fi rm /tmp/temp.txt
Unfortunately, that doesn't work because the utility outputs non-error information to the screen even when it is successful, so it always outputs something, I never need to see it, but I do need to be able to act upon if some of that text says "error" or "connection timed out"
I want to prefix the number of ✔ to corresponding row If I use the command :.s/✔//gn I get output written like '2 matches on 1 line' How can I extract the '2 matches' in above case ?
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'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?
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 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.
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 have a GPS device which sends in data on port number 5000, i am able to capture the data into a pcap file using tcpdump. Now my problem is, i need to pipe the data into a text file as and when data arrives into the pcap file continuously.I did extensive search, but to no avail. been trying to solve this for the past 3 days. I use the following commands to capture and pipe the data, but that happens only once when i issue the command. I want this to happen continuously as and when the data arrives.
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?
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.
if you do the command conky in terminal, it starts conky ofcourse, but it also shows output to that terminal so you can't do any other commands to that terminal, Is their an option like you can do with the '&' sign in other cases? If you do the '&' sign with conky it still gives output, also the conky -d command gives output...
In synaptic package manager when I expand "Details" tab (at the time when some software is installed or removed), I can see a terminal. I want to capture the output of terminal into a file. I tried to highlight and right click. But there is no context menu(copy, cut)
I'd like to write a script that invokes a gnome-terminal session which slowly reads out text like the phosphor screensaver (could be anything, a log file, ascii art, song lyrics, whatev) and then closes. I can invoke a terminal using [gnome-terminal -e 'cat /var/log/dmesg'] but the output flies pass by too quickly.any way to slow it down? I know it seems like an odd request but if anyone has a suggestion I'd love to hear it.
I have searched a lot for solutions of this problem, but there seems to be no solution that works for me. It was time to update my installation... AS I have NEVER updated it. So I ran the update manager and launched updates. Many packages completed, but linux-image-2.6.32-25-generic (2.6.32-25.44) gave me a lot of errors. I don't ave the terminal output from the update manager, but I have info from apt-get install -f. I am using root account.

I've done some searching on googlubuntu for and answer to this but haven't found anything.
As a Linux newbie I was wondering if there are certain types of output from the terminal I should beware of posting for everyone to see? Also are there any codes; that, if I were to be asked to run and report the output on, should raise a red flag?
There is text based game in the Ubuntu repos called gomoku (just 5 in a row) it comes with the package bsdgames. The manual page [URL] lists an option (-b) to run it in the background. I want to try that and if I know how it works create a simple graphical front-end. When I start the program with:
Code: gomoku -b
it starts and remains active, the terminal does not return to prompt which is OK as the command is not finished. The manual says the program reads from stdin, and this might sound stupid but how to get anything there?
I've tried to pipe an echo command to gomoku which works but ends the program after is receives input.
Code: echo "black" | gomoku -b
just finishes. After that when you type another command like:
Code: echo "justsometext" | gomoku -b
gomoku tells it expects either black or white as input. So it forgot the previous "black" because it is a new instance.
I'm writing a couple of programs in C and need to do something to formatting the output. I'm after producing something like a old mainframe screen or early micro where you could PRINT (x,y) to put something on the terminal where you want it. Learning GTK or such is not an option due to time constraints, and some fields need updating frequently during processing, so letting the terminal scroll is going to drive the operator up the wall pretty quickly.
When I type (in new 10.10) soem cmdline comands like "ls -l" then some of the directories have a different fore-and background color (e.g. black on green) while the remaining other directoreis are blue on white.
Where can I find out the meaning of the diferent colors and how can I change them?
If I go to menu
Terminal->Edit->Profile Preferences->Color
then I can set only the full overall background and foreground color. But here only certain parts have a different color. the main color (black on white) is suitable. I do not use system theme.
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
if i will sound stupid but i can't find a command that would echo output of some command. Let's say that i want to echo the third line of ls -a. I know of the tail command but this command starts from behind.
I have a server client prog in which server is my 'agent' and client is 'manager'. Following is the code for both agent and manager. I want my agent to send what manager is requesting. But it is not working the way I want. The parameters which manager is requesting, agent has to send to manager but in this program result for those parameters is shown on agent's own terminal window. Where as I want them on manager's window. Secondly, there result is not correct, means it is giving ' 0 K ram and 0 no of process....
I am trying to display a text using crontab. My settings :
*/2 * * * * /bin/echo "hello"
This setting sends a mail to the user, instead of displaying on the screen. Now tried changing the setting to:
*/2 * * * * /bin/echo "hello" > /dev/tty1
Now I can see the text on the screen, but this setting comes with a catch. What would happen if the user changes the terminal. for instance if he gets into tty2, he wont have write access on tty1. So the user gets a mail saying "permission denied". Is there any way that I can force the user to use a particular terminal or can a cron job be set in a way such that the user would get the text irrespective of the terminal he logs in.
