Hi folks,


Please advise which command/command line shall I run;

1) to display the command and its output on console
2) simultaneous to save the command and its output on a file


I tried tee command as follows;

$ ps aux | grep mysql | tee /path/to/output.txt

It displayed the command and its output on console but only saved the
output on output.txt without the command executed.


2)
$ ls -l | tee -a /path/to/outpu.txt

The output was added to the file also without the command.


3)
$ locate test.txt | tee -a /path/to/output.txt
locate: warning: database `/var/cache/locate/locatedb' is more than 8
days old

It won't add the warning on the file.


Please help. TIA

to get errors and warnings in the output file, you need to redirect them

Hi Yogesh Sawant,


I got it. Thanks.


Leaving behind is how to save the command together with its output on the file.

Perhaps the script command would be closer to what you are looking for. Or you can run the shell with tee, something like

You'd put your canned commands in commands.txt (mainly because typing anything into a shell which is running with redirection is not exactly user-friendly).

Hi era,


Thanks for your advice.


What does commands.txt refer to?


e.g. to run "ls -l" command. What will be the complete command line? TIA

Yeah, something like echo ls -l | sh -ix and if it looks like you want it, add the tee

To my amazement, I found that at least bash in sh mode works pretty well interactively even with the redirection to tee. Maybe you don't have to put your commands in a file after all.

Hi era,


Noted with thanks.


script command solves my problem.

$ script /path/to/output.txt

$ run other commands

$ exit
save all output including commands on the file.

$ script -a /path/to/output.txt
resume script and continue adding output on the file.


Thanks
