Re: Process File Different Way Based on Passed in Argument

in reply to Process File Different Way Based on Passed in Argument

Hi,

If you use '==' to compare strings you will get error as below

Argument "sqlerrors" isn't numeric in numeric eq (==) at args.pl line 11, <FILE> line 1.
Argument "sqlerrors" isn't numeric in numeric eq (==) at args.pl line 11, <FILE> line 1.
Argument "othererrors" isn't numeric in numeric eq (==) at args.pl line 17, <FILE> line 1.
Argument "missingfile" isn't numeric in numeric eq (==) at args.pl line 23, <FILE> line 1.

eq is for comparing strings; == is for comparing numbers.

== does a numeric comparison: it converts both arguments to a number and then compares them.

eq does a string comparison: the two arguments must match lexically (case-sensitive)

All is well. I learn by answering your questions...
