hi everyone,
I'm new to shell script.Any one please clear me the following doubts:

1) Is Shell script executes faster than a perl script?
2) How to split a string with a delimiter(eg. \t) and store in an
array in shell script.
3) How do we execute a mysql query in shell script.

thanx in advance.

In most cases, perl uses functions instead of calling UNIX utilities.
Shell scripts depend on calling UNIX utilities because of limited
language capabilities. UNIX utilities are separate programs (=processes)
that need some time to start.

This is simple stuff, please read a beginner's tutorial. You will see
enough examples. btw: String and Array manipulation is the domain of Perl.

Use mysql as a commandline utility (inside shell scripts) or use perl
-MDBD::mysql (DBI and DBD must be compiled/installed before).
