I am not familiar with the perl and awk syntax :-(.
try google
The example I posted:
loop over the file 'infile' and execute 'expression' on each line
Bind to the current line ($_) and search for all occurences of pattern on that line. By default, this operation will work on $_ so that could have been omitted and this part could have been specified as /pattern/g.
In list context, m//g, or simply //g, returns all of the matched occurrences of pattern. So @_ will be a list containing however many occurrences of the pattern existed.
Take the list @_ and tell me how many items it contains.
Check to see if it contains 2 items (occurrences of pattern).
Print the current line from the file if it contains exactly 2 occurrences of the search pattern.... which is what I thought you wanted.
Hi Friends,
I am having a funny problem with grep. When I run
grep 'expr' file.txt
things work fine. But when try to get the line number using the -n option, i.e,
grep -n 'expr' file.txt
I get a message, "grep: 0652-226 Maximum line length of 2048 exceeded."
If the line has more than... (3 Replies)
I need to search and count the occurrences of a pattern in a file. The catch here is it's a pattern and not a word ( not necessarily delimited by spaces). For eg. if ABCD is the pattern I need to search and count, it can come in all flavors like (ABCD, ABCD), XYZ.ABCD=100, XYZ.ABCD>=500,... (6 Replies)

I need to reduce a file's size below 50MB by deleting chucks of text. The following sed does this.
sed '/^begpattern/,/endpattern/d' myfile

Or can awk... (8 Replies)

fnmatch
FNMATCH(3) Linux Programmer's Manual FNMATCH(3)NAME
fnmatch - match filename or pathname
SYNOPSIS
#include <fnmatch.h>
int fnmatch(const char *pattern, const char *string, int flags);
DESCRIPTION
The fnmatch() function checks whether the string argument matches the pattern argument, which is a shell wildcard pattern.
The flags argument modifies the behavior; it is the bitwise OR of zero or more of the following flags:
FNM_NOESCAPE
If this flag is set, treat backslash as an ordinary character, instead of an escape character.
FNM_PATHNAME
If this flag is set, match a slash in string only with a slash in pattern and not by an asterisk (*) or a question mark (?)
metacharacter, nor by a bracket expression ([]) containing a slash.
FNM_PERIOD
If this flag is set, a leading period in string has to be matched exactly by a period in pattern. A period is considered to be
leading if it is the first character in string, or if both FNM_PATHNAME is set and the period immediately follows a slash.
FNM_FILE_NAME
This is a GNU synonym for FNM_PATHNAME.
FNM_LEADING_DIR
If this flag (a GNU extension) is set, the pattern is considered to be matched if it matches an initial segment of string which is
followed by a slash. This flag is mainly for the internal use of glibc and is implemented only in certain cases.
FNM_CASEFOLD
If this flag (a GNU extension) is set, the pattern is matched case-insensitively.
FNM_EXTMATCH
If this flag (a GNU extension) is set, extended patterns are supported, as introduced by 'ksh' and now supported by other shells.
The extended format is as follows, with pattern-list being a '|' separated list of patterns.
'?(pattern-list)'
The pattern matches if zero or one occurrences of any of the patterns in the pattern-list match the input string.
'*(pattern-list)'
The pattern matches if zero or more occurrences of any of the patterns in the pattern-list match the input string.
'+(pattern-list)'
The pattern matches if one or more occurrences of any of the patterns in the pattern-list match the input string.
'@(pattern-list)'
The pattern matches if exactly one occurrence of any of the patterns in the pattern-list match the input string.
'!(pattern-list)'
The pattern matches if the input string cannot be matched with any of the patterns in the pattern-list.
RETURN VALUE
Zero if string matches pattern, FNM_NOMATCH if there is no match or another nonzero value if there is an error.
