Shell Scripting

Hi,

I have a script where a variable has multiple lines.
How can i count the no. of lines in it in a script.

Ex: PIDS="1234
2345
3455"

PIDCNT=??????


Thanks

Once you put the contents in a variable are you sure they are still individual lines? Maybe the newlines have been lost in the translation and all you have are just words

PIDCNT=`echo ${PIDS} | wc -w`

just a thought.
