unix scripting: check file content

Hi Experts,
I need a way  to checks a file on content;  it should check on either the number of lines (e.g. 3) or on 3 specific strings in that file.
If that check returns that the file has three lines (or has those 3 specific strings in it), then next cmd can be executed.
Shell is ksh.
Thanks for  your help.

Another option:


if [[ `wc -l <MyFile.txt` -eq 3 ]] 
then
  echo "Exec_My_Script(1)"
else
  n=0
  for w in String1 String2 String3
  do
    ((n+=`grep -c $w MyFile.txt`))
  done 
  [ $n -eq 3 ] && echo "Exec_My_Script(2)"
fi

this one is for bash

i=0
while read line
do
      i=`expr $i + 1`
done < test
echo "i is $i"
j=0
line=`less test | grep "string pattern to match" | wc -c`
echo $line
if [ $i -gt 2 -o $line -gt 0 ]
then
      echo "execute command"
fi

Try this:


if [[ `wc -l <MyFile.txt` -eq 3 || `egrep -c '[Word1&&Word2&&Word1]' MyFile.txt ` -gt 0 ]] 
then
  echo "Exec_My_Script"
fi
