In bash, I need to send the STDOUT and STDERR from a command to one file, and then just STDERR to another file. Doing one or the other using redirects is easy, but trying to do both at once is a bit tricky. Anyone have any ideas? (9 Replies)
If I forget to set up stderr redirection on execution of a script, is there a way to set that redirection post-exec? In other words, if I have a script running and no errors are being logged... and then I remember that I forgot the 2>&1 on the script... can I turn it on after the fact?

2 > &1 | tee file works but it also displays the non error messages to file, while i only need error messages.

print $0 > FILENAME

Hi folks
I need/want to redirect output (stdout, stderr) from an exec call to separate files. One for stderr only and two(!) different (!) ones for the combined output of stderr and stdout.

bup-newliner(1) General Commands Manual bup-newliner(1)NAME
bup-newliner - make sure progress messages don't overlap with output
SYNOPSIS
<any command> 2>&1 | bup newliner
DESCRIPTION
bup newliner is run automatically by bup. You shouldn't need it unless you're using it in some other program.
Progress messages emitted by bup (and some other tools) are of the form "Message ### content", that is, a status message containing a vari-
able-length number, followed by a carriage return character and no newline. If these messages are printed more than once, they overwrite
each other, so what the user sees is a single line with a continually-updating number.
This works fine until some other message is printed. For example, progress messages are usually printed to stderr, but other program mes-
sages might be printed to stdout. If those messages are shorter than the progress message line, the screen will be left with weird looking
artifacts as the two messages get mixed together.
bup newliner prints extra space characters at the right time to make sure that doesn't happen.
If you're running a program that has problems with these artifacts, you can usually fix them by piping its stdout and its stderr through
bup newliner.
