I am trying to get a text value between 2 words in a string and assign it to a value. Basically the program should read each row in a file and return the text between 2 fields and print it to another file.
How will you change the 5th column in the data file with the value in the second column in the error_correction.txt file.
You have to match an extra variable, column 3 of the error_correction file with column 6 of the data.txt file.

I am completely new to perl programming. My father is helping me learn said programming language. However, I am stuck on one of the assignments he has given me, and I can't find very much help with it via google, either because I have a tiny attention span, or because I can be very very dense.

match - Match strings against glob paterns
SYNOPSIS
match [-gilrqs] [-n <n>] [-c cmd] [-x code] {[-p] pattern | -f <file>} str1 [str2 ...]
DESCRIPTION
match checks strings against pattern, which should be a shell-like glob pattern. pattern may contain the following special characters:
? A "?" character in pattern matches any single character in the string, except that the "/" character is only matched if match was given
the -s option.
* A "*" character in pattern matches zero or more characters in the string. The exception is that it will only match "/" characters if
match was given the -s option.
[...]
A set of characters between square brackets matches any character in the set. In addition, the "-" character can be used to specify a
range. For example "[+e0-3]" would match any of the characters "+", "e", 0, 1, 2, or 3 in the input string. To include a hyphen ("-")
in the set of characters matched, either include the hyphen first or last, or escape it with a "".
[!...]
A character class preceded by a "!" matches any character but those specified in the class. The exception is that the negated
character class will match a "/" only if match was given the -s option.
c The backslash character escapes the next character c. Thus, to match a literal "*", you would use the pattern "*".
match prints each string that matches pattern, one per line, and exits 0 if one or more strings matched. If no string matches, match exits
with status 67 (or whatever alternate status was specified by the -x flag). If the -n n flag was specified, match prints only the text
that matched the nth occurrence of "*" in the patten.
OPTIONS
-f file
Specifies that the pattern should be read from file. match will read each line of the file and consider it as pattern to match against
the argument strings. For each argument string, match stops when it hits the first matching line of the file. If file does not exist,
match exits 67, or whatever code was specified by -x.
-g Normally, the -n option selects text matching particular "*" characters in the patern. -g changes this behavior to use parentheses for
grouping. Thus, for instance, the text "foo.c" would match pattern "*(.[ch])", and the output with option -n 1 would be ".c". To
include a literal "(" or ")" in the pattern with the -g option, you must precede the character with a "".
-i Makes the match case insensitive. str will be considered to match if any variation on its capitalization would match. For example,
string "G" would match pattern "[f-h]".
-l When a pattern matches the string in more than one way, the -l flag says to assign as much text as possible to the leftmost "*"s in the
pattern. For example, pattern "*+*" would match text "a+b+c", and the first "*" would match "a+b". This behavior is the default, thus
-l's effect is only to undo a previous -r flag.
-n n
With this flag, match prints the text that matched the nth "*" in the pattern, as opposed to printing the whole string. The leftmost
"*" corresponds to -n 1. Specifying -n 0 causes match to print the whole matching string. Specifying -n -1 or using a value greater
than the number of "*"s in the pattern causes match not to print anything, in which case you can still use the exit status to see if
there is a match. The default value for n is 0, unless -g has also been specified, in which case the default is 1.
-c command
When -c is specified, match runs command with the system shell (/bin/sh), giving it as argument $0 the full string that matched, and as
arguments $1, $2, etc., the parts of the string that matched any "*"s in pattern. If the command does not exit with status 0, match
will exit immediately, before processing further matches, with whatever status command returned. The -c and -n flags are mutually
exclusive.
-p pattern
Specifies the pattern to match against. The -p flag is optional; you can specify pattern as the first argument following the options.
However, if you want to try matching the same input string against multiple patterns, then you must specify each pattern with a -p
flag.
-q This option is synonymous with -n -1; it suppresses output when there is a match. You can still determine whether a match occurred by
the exit status.
-r When a pattern matches the string in more than one way, the -r flag says to assign as much text as possible to the rightmost "*"s in
the pattern. For example, with -r, pattern "*+*" would match text "a+b+c" with the "*" matching "a", and the second matching "b+c".
-s Ordinarily, "*", "?", and negated character classes ("[!...]") do not match "/" characters. -s changes this behavior to match slashes.
-x code
By default, when there is no match, match exits with status 67. With this option, match exits with status code, instead.
EXAMPLES
Suppose you have a directory with a bunch of files ending .c and .o. If, for each file named foo.c you want to attempt to delete the file
foo.o, you can run the following command:
match -p '*.c' -c 'rm -f $1.o' *.c
Servers running the mailman list manager often send mail from bounce addresses of the form listname-bounces@host.com. If you subscribe to
multiple lists on the same server, the mailman interface makes it easier if you subscribe under the same address. To split the mail into
multiple folders based on the bounce address in the environment variable SENDER, you might chose a mailbox with the following shell code:
name=`match -n1 "*-bounces@host.com" "$SENDER"`
&& echo "$HOME/Mail/incoming/host-$name.spool"
