Thanks, Pravin for the helpful reply. The code work perfectly at command prompt. Would you please further help on how to do an iteration script for multiple files in directory using the code you gave ? I tried this:
Code:
!/bin/bash
for d in `ls *`
do
awk 'NR==FNR{a[$5]=++i;next} { if ( $5 in a) {print $0}}' $.xyz $.txt > EF_$d
done
The $.xyz and $.txt have same numeric string, and only file extension differs.
The EF_$d is to write the output correspondingly.
I have a file name in $f. If $f has "-" at the beginning, or "=", or does not have extension ".ry" or ".xt" or ".dat" then cerr would not be empty.
Tried the following but having some problems.
set cerr = `echo $f | awk '/^-|=|!.ry|!.xt|!.dat/'` (4 Replies)
I have the following in an awk script. I want to do them on condition that: fext == "xt"
FNR == NR {

}
FNR in idx { v = val] }
{ !/>/ && srdist = abs($1 - v) }
/>/ || NF == 2 && srdist < dsrmx {... (1 Reply)
Dear awk users,
I am trying to use awk to match records across two moderately large CSV files. File1 is a pattern file with 173,200 lines, many of which are repeated. The order in which these lines are displayed is important, and I would like to preserve it. File2 is a data file with 456,000... (3 Replies)

Hi,

Hi,
I have requirement to find the matching patterns of two files in Unix. One file is the log file and the other is the error list file. If any pattern in the log file matches the list of errors in the error list file, then I would need to find the counts of the match.
For example,

glob
GLOB(3) 1 GLOB(3)glob - Find pathnames matching a patternSYNOPSIS
array glob (string $pattern, [int $flags])
DESCRIPTION
The glob(3) function searches for all the pathnames matching $pattern according to the rules used by the libc glob() function, which is
similar to the rules used by common shells.
PARAMETERS
o $pattern
- The pattern. No tilde expansion or parameter substitution is done.
o $flags
- Valid flags:
o GLOB_MARK - Adds a slash to each directory returned
o GLOB_NOSORT - Return files as they appear in the directory (no sorting). When this flag is not used, the pathnames are
sorted alphabetically
o GLOB_NOCHECK - Return the search pattern if no files matching it were found
o GLOB_NOESCAPE - Backslashes do not quote metacharacters
o GLOB_BRACE - Expands {a,b,c} to match 'a', 'b', or 'c'
o GLOB_ONLYDIR - Return only directory entries which match the pattern
o GLOB_ERR - Stop on read errors (like unreadable directories), by default errors are ignored.
RETURN VALUES
Returns an array containing the matched files/directories, an empty array if no file matched or FALSE on error.
Note
On some systems it is impossible to distinguish between empty match and an error.

EXAMPLES
Example #1
Convenient way how glob(3) can replace opendir(3) and friends.
<?php
foreach (glob("*.txt") as $filename) {
echo "$filename size " . filesize($filename) . "
";
}
?>
The above example will output something similar to:
funclist.txt size 44686
funcsummary.txt size 267625
quickref.txt size 137820
NOTES
Note
This function will not work on remote files as the file to be examined must be accessible via the server's filesystem.
Note
This function isn't available on some systems (e.g. old Sun OS).
Note
The GLOB_BRACE flag is not available on some non GNU systems, like Solaris.
