Shell Programming and Scripting

Hi

Anyone can compare and contrast differences, Advantages & Disadvantages between BASH vs PERL

just a need few points on both

Thanks

Hi,
Perl uses more resources but can do a lot more with less hastle then bash.
I would use bash for a "light scripting" ...

perhaps, if you are doing system programming or administration, then
bash (ksh93) has a more natural and native set of keywords and
semantics, as the underlying command line shell.

if one's task involves lots of data processing requiring complex
data structures, then perhaps Perl would be worth the extra
trouble^h^h^h^h^h^h^h richness.

For anything involving mainly the manipulation of files, external commands, or processes, I'd use Bash (or, more correctly, a shell script). For anything involving mainly the manipulation of structured data, I'd use Perl. For anything involving both, I'd use both (to the extent that the problem isn't so simple that you can handle it with sed or awk; and even then, Perl is often a good choice).

Perl has a lot of strengths specifically because it was designed as a glue language to "fill in the gaps" where system calls or data structures were not straightforward to handle with existing tools; arguably, the end result isn't always very elegant, but it often gets the job done where previously you would have had to resort to a small custom C program.

thanks to all
