echo " test_sys_job" | grep test

Code:

echo "----------------- test_sys_job -----------------" | grep -e "-----------------"

'-e' has got nothing to do with it.

Code:

echo "----------------- test_sys_job -----------------" | grep -- "-----------------"

are you sure? I've tested using AIX and it works

doesn't work on Solaris.
The problem is with the to be searched pattern - '---' - grep thinks you're specifying the command line option that begins with a '-' AND it's complaining about 'usage'.
By specifying '--' and a pattern '-----------' you're telling grep after the '--' there're no more options.

Check the following :

echo "----------------- test_sys_job -----------------" | grep '\---------------'

\ is used for any special char.

Works fine on Suse.

change to nawk

Code:

echo "--------- .... -----" | nawk '/--------/'
