Read each line from file1 and file2 and perform <perl expression> on each line.
If the line consists of a single integer number, append it to variable x using | as a separator. The ^ is beginning of line, the $ is end of line and (\d+) represents one or more decimal digits. After your file1 example is processed, $x will equal |100|103|104|108.
If the line is not a single integer (then it will be your entries from file2), strip the first character off of variable x and save what remains in y. This is inefficient because it has to be done for each line that is processed. This places 100|103|104|108 in y. Print the line if it contains any of the strings in variable y located between two | characters.
Hi All,
as you can see I'm pretty new to this board. :D
I'm struggling around with small script to search a few fields in another file.
Basically I have file1 looking like this:

15:38:29 sz:10003 pr:19.28

I need to find matches for any lines in file1 that appear in file2. Desired output is '>' plus the file1 term, followed by the line after the match in file2 (so the title is a little misleading):

I am trying to use awk to find all the $2 values in file2 which is ~30MB and tab-delimited, that are between $2 and $3 in file1 which is ~2GB and tab-delimited.

will always be NM_ and the end pattern is always ;... (2 Replies)
Hi
Does anyone know of an efficient way to index a column of data in file2 to print the coresponding row in file1 which corresponds to the data in file2 AND 30 rows preceding and after the row in file1.
For example suppose you have a list of numbers in file2 (single column) as follows:... (6 Replies)

comm
comm(1) User Commands comm(1)NAME
comm - select or reject lines common to two files
SYNOPSIS
comm [-123] file1 file2
DESCRIPTION
The comm utility reads file1 and file2, which must be ordered in the current collating sequence, and produces three text columns as output:
lines only in file1; lines only in file2; and lines in both files.
If the input files were ordered according to the collating sequence of the current locale, the lines written will be in the collating
sequence of the original lines. If not, the results are unspecified.
OPTIONS
The following options are supported:
-1 Suppresses the output column of lines unique to file1.
-2 Suppresses the output column of lines unique to file2.
-3 Suppresses the output column of lines duplicated in file1 and file2.
OPERANDS
The following operands are supported:
file1 A path name of the first file to be compared. If file1 is -, the standard input is used.
file2 A path name of the second file to be compared. If file2 is -, the standard input is used.
USAGE
See largefile(5) for the description of the behavior of comm when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).
EXAMPLES
Example 1: Printing a list of utilities specified by files
If file1, file2, and file3 each contain a sorted list of utilities, the command
example% comm -23 file1 file2 | comm -23 - file3
prints a list of utilities in file1 not specified by either of the other files. The entry:
example% comm -12 file1 file2 | comm -12 - file3
prints a list of utilities specified by all three files. And the entry:
example% comm -12 file2 file3 | comm -23 -file1
prints a list of utilities specified by both file2 and file3, but not specified in file1.
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of comm: LANG, LC_ALL, LC_COLLATE,
LC_CTYPE, LC_MESSAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 All input files were successfully output as specified.
>0 An error occurred.
