Hi ,

I have seen some log files where they have captured the command that is being executed, comments present in the scripts and the out put of the command as well, through scripts. could any one of you please let me know how do i do that?

Thanks in advance.

Cheers,

echo "yourcommand args" > log_file.txt
yourcommand args >> log_file.txt

{
    set -x
    yourcommand args
    set +x
} > yourlog.txt 2>&1

Oh- i never knew that, you could capture even the comments b tracing. i guess, you are right, as they are using set -vf probably thats how they are accomplishing this.


also, incase of command failures will the script teminate? like, in the below code, the file is not found so i want the script to terminate? if yes, then, how do i avoid from script terminating. for instance, i would want to ignore even if the file is not present and continue running the next commands?????

{
set -x
rm filename
rm: could not find the file
set +x

No, the script will not terminate unless you want it to.

if ! rm filename
then
    exit 1
fi

Hey thanks for your reply.

as i do not have the access to a unix box right now, so i will try it later.

Many Thanks,
