OK, so the median is based on data we don't see, and we just pick the middle without regard to any order but the given one. But I still don't understand.
4 makes sense for cat, being (2+6)/2, but how does one get 3 for dog? That's the last element, not the middle. I wondered if maybe they were line numbers instead, but that doesn't make sense either.

Trying to match $1 of target.txt to $5 of file.txt. If there is a match then in an output.txt file $1,$1 (row underneath),$6,$4,$7 from file.txt are printed on the same line as $1 of target.txt. The input is from excel and the output should be tab-deliminated. Thank you :).

I am trying to create a cronjob that will run on startup that will look at a list.txt file to see if there is a later version of a database using database.txt as the source. The matching lines are written to output.
$1 in database.txt will be in list.txt as a partial match. $2 of database.txt... (2 Replies)

PCRESAMPLE(3) Library Functions Manual PCRESAMPLE(3)NAME
PCRE - Perl-compatible regular expressions
PCRE SAMPLE PROGRAM
A simple, complete demonstration program, to get you started with using PCRE, is supplied in the file pcredemo.c in the PCRE distribution.
The program compiles the regular expression that is its first argument, and matches it against the subject string in its second argument.
No PCRE options are set, and default character tables are used. If matching succeeds, the program outputs the portion of the subject that
matched, together with the contents of any captured substrings.
If the -g option is given on the command line, the program then goes on to check for further matches of the same regular expression in the
same subject string. The logic is a little bit tricky because of the possibility of matching an empty string. Comments in the code explain
what is going on.
If PCRE is installed in the standard include and library directories for your system, you should be able to compile the demonstration pro-
gram using this command:
gcc -o pcredemo pcredemo.c -lpcre
If PCRE is installed elsewhere, you may need to add additional options to the command line. For example, on a Unix-like system that has
PCRE installed in /usr/local, you can compile the demonstration program using a command like this:
gcc -o pcredemo -I/usr/local/include pcredemo.c
-L/usr/local/lib -lpcre
Once you have compiled the demonstration program, you can run simple tests like this:
./pcredemo 'cat|dog' 'the cat sat on the mat'
./pcredemo -g 'cat|dog' 'the dog sat on the cat'
Note that there is a much more comprehensive test program, called pcretest, which supports many more facilities for testing regular expres-
sions and the PCRE library. The pcredemo program is provided as a simple coding example.
On some operating systems (e.g. Solaris), when PCRE is not installed in the standard library directory, you may get an error like this when
you try to run pcredemo:
ld.so.1: a.out: fatal: libpcre.so.0: open failed: No such file or directory
This is caused by the way shared library support works on those systems. You need to add
-R/usr/local/lib
(for example) to the compile command to get round this problem.
