Robert, [ Yes, Bjoern, this is OT for the Cygwin list as it's all about shell usage and not at all Cygwin specific. ]
You're using BASH, Robert. Except for the simple ">" and ">>" redirection, it's syntax is different from that of TCSH. Bjoern's answer was for TCSH. I'm a BASH user, so I'll answer for that shell. # Simple redirection of standard output only, overwriting existing file, if any: % echo "foo is bar" >fbfile # Appending redirection % echo "foo is more bar" >>fbfile # Redirect standard error only % command-that-generates-error-output arg1 arg2 2>error-output # Redirect standard output and standard error separately % command arg >stdout 2>stderr # Merge standard error with standard output # Order of redirection operators IS significant % command arg1 arg2 >merged-output 2>&1 All the output redirections can be doubled for appending, but that does not apply to the descriptor merging forms (e.g., 2>&1, which means merge descriptor 2 with the current descriptor 1 and works for any number greater than 0). Good luck. Get a good tutorial that covers BASH.
