check if specified path is in $PATH
echo $PATH | grep "\/usr\/ucb[:$]" is not working using sh-posix
The problem is very simle. I want to check '/usr/ucb' is in the PATH environment variable. If i simply grep '/usr/ucb' i might got wrong result eg '/usr/ucb/bin'. After the path an end of line or colon character should be. In other words: in range expression how can i use special character like $. Thanks in advance FPETER Last edited by fpeter75; 08-29-2008 at 06:53 AM.. |
