[praveen.kantharajapura]

Hi all,

I have a file now i need to search for two strings "string1" and
"string2" in the same line.If both of them occur in the same line
increment a counter else do not.

How to go about doing this in perl??

I have a file

perldoc -f open

now i need to search for two strings "string1" and
"string2" in the same line.

You would write a pattern match to do that.

perldoc -f m

If both of them occur in the same line

See the && operator, also in perlop.pod.

increment a counter else do not.

$counter++;

See above.

Which part is the problem?
- the check if a string is contained in another string? See 'perldoc -f
index'
- to combine two conditions? See 'perldoc perlop', operator 'and'
- to create a if clause? See 'perldoc perlsyn', and then the if
statement in section compound statements
- to increment a counter? See 'perldoc perlop', operator +=
- to do nothing? Well, ....
