symcfg show -sid $SID -pool $i -detail -thin -gb |grep "Max. Subscription Percent"
will return some line which include string Max. Subscription Percent and also Enable in same line ?
Have you tested the command and what is the output in this lines where is Max. Subscription Percent ?
If syntax is
[ is one of the commands. So it's also [[.
But also symcfg, cp, grep, awk, .. are commands.
Ex. testing how cp works
So something: grep output to the /dev/null - not so interesting to see.
But you can also test output of grep.
But if line include "Max. Subscription Percent" and "Enable" in this order, then why not using grep something like
Sorry, but can i insert in to this cycle a command like this?
cat list_vmax_xx_pools
pool_1
pool_2
pool_3
You of course can, there's no syntax error, but the way you present it won't yield a reasonable result. symcfg may output whatever it wants, if you grep for "Max Subscription Percent" the output will never be an "Enable" alone.
Why don't you grep for "pool.*Max Subscription Percent" or even "pool.*Max Subscription Percent.*Enable" (as proposed by kshji) in the first place and then work on the results file? Or, maybe, that's already what you desired?
BTW, kshji's last data evaluation could be condensed to
