How do I remove a substring from a string using sed?
For example: I need to remove from all this:
/opt/openet/cdm/applications/SubscriptionManager/fwhome/config/log/corCTE_SM.pid process 18312 is not running
everything before CTE_SM and after too.
I need to extract CTE_SM from this line.
How do I do this?
Thank you so much.

assuming that your string is always has capitals, I am replacing the lowercase letters & then splitting the string using awk.
you can try splitting the text even before replacing with sed.
myString='/opt/openet/cdm/applications/SubscriptionManager/fwhome/config/log/corCTE_SM.pid process 18312 is not running'
echo $myString | sed 's/[a-z]//g' | awk -F/ '{print $(NF)}' | awk -F. '{print $1}'
result= CTE_SM
alternatively
echo $myString | awk -F/ '{print $(NF)}' | awk -F. '{print $1}'
result= corCTE_SM
