Is there a l link to a brief summary of perl (5-10 pages)?
What is the proper syntax to set LC_ALL for within a perl script?
I want to run linux commands like sort, grep, uniq from within a perl
script.
But I want them to optionally continue to act like pipes.
For example,
I want ./perlsort to ac

When I do string comparisons in perl the strings seem to ignore the
embedded hyphens.
I want to sort strings assuming the 'dictionary' order of the chars is
ASCII order: hypen, 0-9, A-Z.
It appears linux sort also has the problem (LC_ALL is blank).
Any ideas? I want to avoid a brute force char by c

Problems:
1) it runs out of memory 8Gig of files with 2GB RAM
2) it as
I've got two similar large files with one word per line and they're
sorted.
Each file has a few words not in the other.
I typically identify the unique words in the file using diff,grep,cut.
When the files are too big (2Gig) diff dies with "memory exhausted".
I want to search for the unique words
Worked great.
One additional thing,
I want to use it as is with two args
or, if only one arg is passed, then data_file comes from stdin?

I have two sorted files (one string per line).
[I'd also like to know how to sorvle this if the lists weren't sorted
(as complimented sets)].]
I want to output the List1 items not found in the List2 file.
grep is too slow.
diff gets stuck because list2 has millions of items.
for example:
List1.txt
12 matches
Mail list logo
