This is important, because sometimes I will want to separate the output to two files using redirections. The problem is this: $ ./command zsh: no such file or directory: ./command Sometimes the command I have to run won't exist, so zsh will issue that error. How the heck can I make zsh not to spill the error message but at the same time let the command to use stderr and stdout? I mean, I can silent zsh doing this: $ ./command 2> /dev/null but that will silent the stderr output from the command if the command exists. I cannot use MULTIOS and I cannot use any special option of zsh because of portability, so... can this be done? Can I use any subshell trick to do the job? The only solution I've found so far is to pipe stderr thru a sed script and get rid of any shell message, but it is too much... Other solution is doing something like this: $ { ./command 2>&1 } 2> /dev/null but then I completely loose the ability of separating the stdout output from the stderr one :( Thanks a lot in advance :) and sorry for the weird question O:) Raúl Núñez de Arenas Coronado -- Linux Registered User 88736 | http://www.dervishd.net http://www.pleyades.net & http://www.gotesdelluna.net It's my PC and I'll cry if I want to...
