Sorting by length

http://www.unix.com – Hello, I have a very large file: a dictionary of headwords of around 40000 and would like to have the dictionary sorted by its length i.e. the largest string first and the smallest at the end. I have hunted for a perl or awk script on the forum which can do the job but there is none available. I am a newbie to Perl and more accustomed to C programming. The C program I wrote takes ages and I believe Perl or Awk are blazing fast. Could anybody provide me with a script and if possible help me out by useful comments so that I can start off writing scripts on my own. Many thanks for your kind (HowTos)

I am currently in Afghanistan and do not have access to some of the resources I normally do back in the US. Just accessed this site and it looks promising! Hopefully you will not find my question too much of a waste of your time. I write mostly Korn Shell and PERL on Solaris systems for the Army.

Can't run perl scripts 50 weeks 1 day ago

I am trying to run a perl script with the header #!/user/bin/perl -w

When I try to run the script the terminal returns

@localhost Begperl]$ ./circumfrence.plx bash: ./circumfrence.plx: /user/bin/perl: bad interpreter: No such file or directory

I am a novice writing perl scripts so I'd appreciate any help you guys can offer. I have a list of 100 words in a file (words.txt) and I need to find them in a second file (data.txt). Whenever one of these words is found I need to write that line to a third file (out.txt) and then continue searching for more matches.

Please show me how to make substitution over the contents of a file in a perl script.

In a perl script, the core part of substitution operation is

s/FINDPATTERN/REPLACEPATTERN/g;

However, I cannot figure out how to make the substitution occur over the contents of a file.

Greetings all,

If I have a SH script that calls a PERL script in the following way:

Code: perl $HOME/scripts/config.properties And in the config.properties PERL file, this Perl script only sets a number of environmental parameters in the following way:

Code: #!/usr/bin/perl $VAR1 = (     'PECOSSource' => '/opt/tibco/incoming',     'PECOSDestination' =&gt

I'm not sure if this forum covers PERL issues but here I go:

I'm trying to run a PERL script from Notepadd++. I've entered the path of the script from the run command but it is only opening a blank window. Is there anything else that needs to be done when using the 'RUN' feature of Notepad++?
