I want to check in a shell script whether subversion is installed. For that I chose to check the exit code after the program has been executed. I tried using command svn, but that prints out the output of the command (Type 'svn help' for usage.). If I suppress it with 2>/dev/null the result is an empty string.

How could I make it work?

The exit code of the last executed program is stored in $?.

@shellholic - do you, by any chance, know, how to do the same in Windows? I'm writing the same script for both Windows and Linux. – jurchiks Feb 12 '11 at 21:05
