Have a look at this page for the complete list of test-expression used with if
Code:
[[ -N filename ]] && echo yes || echo no
-N option - True if FILE exists and has been modified since it was last read. I guess this is what you are looking for!
#!/bin/sh
It does not work. It gives me only NO. $3 $4$5$6 my files
file=$1
target=$2
while read line
do
if [ "$line" != "" ]
then
set $line
if [ "$1" = "$target" ]
then
if [ "$2" = ":" ]
then
for i in $3 $4 $5 $6
do
-N i && echo yes || echo no
done
fi
fi
fi
done< $file
