in tcsh I'm trying to redirect STDERR from a command from my .aliases file.
I found that I can redirect STDERR from the command line like this. . .
$ (xemacs > /dev/tty) >& /dev/null
. . . but when I put this in my .aliases file I get an alias loop. . .
$ cat .aliases
alias xemacs '(xemacs > /dev/tty ) >& /dev/null'
$ xemacs &
Alias loop.
$
. . . so I put a backslash before the command in .aliases, which allows the command to run. . .
$ cat .aliases
alias xemacs '(\xemacs > /dev/tty ) >& /dev/null'
$ xemacs &
[1] 17295
$
. . . but now I can't give the command any arguments:
$ xemacs foo.txt &
Badly placed ()'s.
[1] Done ( \xemacs > /dev/tty ) >& /dev/null
$
Can anyone offer any solutions? Thank you in advance!
UPDATE: I'm still curious if it's possible to redirect STDERR in tcsh from .aliases, but as has been suggested here, I ended up with a shell script:
#!/bin/sh
# wrapper script to suppress messages sent to STDERR on launch
# from the command line.
/usr/bin/xemacs "$@" 2>/dev/null
I suspect this is a case where NOT using an alias is the best option - try using a shell script instead:
#!/bin/tcsh
(xemacs $* > /dev/tty ) >& /dev/null
