many files can't find

[warmsuns]

yao@ubuntu:~/perl$ perl abstract_extractor_by_ting 2.txt
sort: open failed: words_in_SENTENCES: No such file or directory
uniq: SENTENCES_words_sort: No such file or directory
sh: 1: spell: not found
uniq: words_in_SENTENCES_words_comb: No such file or directory
sh: 1: spell: not found
sort: open failed: SENTENCES_WORDS_root: No such file or directory

This is the problem I encounted ,and the following is the code where the above missing files are used

#!/site/bin/perl

system("perl5 sentence_words SENTENCES ADDED_WORDS_LIST");

system("sort -f -o SENTENCES_words_sort words_in_SENTENCES");

system("uniq SENTENCES_words_sort > SENTENCES_words_sort_uniq");

system("mv SENTENCES_words_sort_uniq words_in_SENTENCES");

system("perl5 word_extract2 words_in_SENTENCES");

unlink(words_in_SENTENCES);

unlink(SENTENCES_words_sort);

unlink(SENTENCES_words_sort_uniq);

system("spell -v +ADDED_WORDS_LIST words_in_SENTENCES_words > SENTENCE
+S_err");
open(IN,"SENTENCES_err");
open(OUT,"> SENTENCES_err_list");
loop1:while(<IN>) {
     if (/^[+-]/) {
        last loop1;
     }
     print OUT $_;
}
close(IN);
close(OUT); 
   
unlink(SENTENCES_err);

system("perl5 generate_combinations words_in_SENTENCES_words SENTENCES
+_err_list");

unlink(words_in_SENTENCES_words);

unlink(SENTENCES_err_list);

system("uniq words_in_SENTENCES_words_comb > SENTENCES_WORDS");

unlink(words_in_SENTENCES_words_comb);

system("spell -v +ADDED_WORDS_LIST SENTENCES_WORDS > SUBJECT_WORDS_v")
+;

system("perl5 find_root SENTENCES_WORDS SUBJECT_WORDS_v");

unlink(SENTENCES_WORDS);

unlink(SUBJECT_WORDS_v);

system("sort -f -o SENTENCES_STEM SENTENCES_WORDS_root");

unlink(SENTENCES_WORDS_root);

system("perl5 keyword_subject SENTENCES_STEM SENTENCES_words");

unlink(SENTENCES_words);

there are many commands used in the program, like "perl5 " and the two files names follows with the "sort"command ,I just can't get the meaning from these.I am studying some code written by someone else,but I have to let it run successfully and later transfer them on the windows platform. Can someone give me some useful advice:) Thank you so so much:)

First off you need to note that system runs a command on your OS. This is almost a shell script.

Your code uses the following *nix commands:

1. sort
2. uniq
3. mv
4. spell

Additionally it runs certain Perl scripts, ( The perl5 ... bit ) and redirects the output to files that are then subsequently sorted, moved, deleted ...

To get this to work you either need to call your other Perl programs as functions and user Perl to sort and uniq and so on OR you need to find windows equivalents to each of these commands, and make sure that they work from command line before creating a script with it.

"...and later transfer them on the windows platform"

Take a look at cygwin for the needed unix tools for windoz.

Hi warmsuns,

Are you using
use strict;
use warnings;
in your code?

As your error message says, the script could not find the files. give the absolute path to the file names

[Anonymous Monk]

Are you using use strict; use warnings; in your code?

How exactly does this help the OP? The code provided does not have problems when strict and warnings are added.

As your error message says, the script could not find the files.

The OP knows that:

This is the problem I encounted ,and the following is the code where the above missing files are used

And the gem:

give the absolute path to the file names

Of course that will help with:

there are many commands used in the program, like "perl5 " and the two files names follows with the "sort"command ,I just can't get the meaning from these.
