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

DESCRIPTION
The line command copies one line, up to and including a newline, from standard input and writes it to standard output. Use this command
within a shell command file to read from your terminal. The line command always writes at least a newline character.
NOTES
The line utility has no internationalization features and is marked LEGACY in XCU Issue 5. Use the read utility instead.

Success. End-of-File.
EXAMPLES
To read a line from the keyboard and append it to a file, enter: echo 'Enter comments for the log:' echo ': c' line >>log
This shell procedure displays the message: Enter comments for the log:
It then reads a line of text from the keyboard and adds it to the end of the file log. The echo ': c' command displays a : (colon)
prompt. See the echo command for information about the c escape sequence.
