I want to find total number of files haivng nothing in feild 1 using awk
will command
awk -F "|" '( $1=="") {print NR}' test_awk
will work???
awk -F"|" ' $1 == "" { cnt++ ; } END { print cnt } ' file
good to know such command
can you explain about cnt
cnt is a variable.
$1 == "" { cnt++ ; }
cnt is incremented if the first field is null
You can also use grep :
grep -c '^|' file
