linux/bash output redirection

[Red Squirrel]

Is there a way to do a &> output redirection (everything, even errors) but make it append? I figured &>> would work, but it errors out.

myabe this will help?

 

[xcript]

command >> foo 2>&1, IIRC.

Won't 2> only output errors though? I want to output (append) everything, errors, non errors. It's for a weird UPS software that outputs stuff at random places including the server's main console which is never looked at.

 

[Nothinman]

command 2>&1 >>file

works fine here.

>>foo is sending stdout to the file, 2>&1 is sending stderr to wherever stdout is going.

OH I see, I did not figure I could actually use 2>&1 >>. I thought &1 would be treated as a file because it's after >.

Oddly enough there's a section in the bash man page called "Redirecting Standard Output and Standard Error"
