Shell Programming and Scripting

We interrupt this thread to bring you a special Unix.com news report:

Resident Ruby Wrangler attacks Perl's string processing. Everyone make sure to stock up on water and canned goods. We are now at DEFCON 2.

hehehe.

Alister

my suggestion：

Code:

ls|grep -cE "aaa"

regard.

you are misunderstand what i written. I did not say Perl is no good for string processing, so the word "attack" is , IMO, not really appropriate. what i merely wanted to say is, tools such as awk, Python, Ruby, PHP etc all are as good as Perl for string processing, hence the word "overhyped". Perl has its days where its an excellent tool for text/string processing, however with the proliferation of programming languages in this age, most of them are as capable to do this job.

Code:

awk -vx="aaa" '{for(i=0;++i<=NF;){if($i==x){++n}}}END{print n}' *
