I've got this shell program (part of a home-made sysadmin package):
#!/bin/sh
PING_PROG="/bin/ps -ax | /usr/bin/grep apache"
${PING_PROG}
My thought is that this should run the command(s) contained in PING_PROG.
However, this is the output I get:
root@skippyii# sh -x ./check_apache.sh
+ PING_PROG=/bin/ps -ax | /usr/bin/grep apache
+ /bin/ps -ax | /usr/bin/grep apache
ps: |: No such file or directory
root@skippyii#
I'm thorougly confused. I know this can be done, but I can't seem to
figure out how.
Any help would be appreciated.
