BASH while line numbers in file is smaller than x

Question

i want to make a loop that reads some files and i want it to stop when wc output is smaller than 5 in this case the file "file" contains the names of the files that will be worked on

for i in `cat file`
do

echo printing $i ...
a=`wc $i`
while [ $a -gt 5 ]
do
echo 3
sleep 10
done

done

this part is not working

a=`wc $i`
while [ $a -gt 5 ]

Answer 1

Your going to want to use wc -l to get the line count of the file. Also you will want to decrement $a so you don't have an infinite loop.

Answer 2

a=$(wc -l $i|awk '{print $1}')
