checking variable has value - ksh
hi all,
i have a shell (ksh) script where i am reading line by line from a grep command and i wanted to check if the grep command actually returned something or was null. i can do this by using -z : if [ -z "$myVariable" ]; then ..... but this forces me to do something when $myVariable is null when i would like to just move on to the next line. how do i do that ?? have tried if [ ! -z "$myVariable" ]; then ..... but it threw some errors. many thanks. |
