Find files matching a pattern
Hi,

I am writing a BASH shell script. I would like to count all the files in the CURRENT directory matching a specific pattern. Could someone suggest the best/simplest way to do this. I have thought of these solutions (for simplicity the pattern is all files starting with A):

ls -1 *A | wc -l

OR

find ./ -name "A*" | wc -l

The problem with the first solution is that it returns an error message if there are no files that match the pattern. If this is the case I just want 0 returned.

The problem with the second solution is that it searches the current directory, but also any sub-directories included within.

Any suggestions? Thanks a lot.

Mike

exigrep

EXIGREP(8)						      System Manager's Manual							EXIGREP(8)

NAME

       EXIGREP - Search Exim's main log

SYNOPSIS

       exigrep [-l] pattern [log file] ...

DESCRIPTION

       The  exigrep  utility  is  a  Perl script that searches one or more main log files for entries that match a given pattern.  When it finds a
       match, it extracts all the log entries for the relevant message, not just those that match the pattern.	Thus, exigrep can extract complete
       log entries for a given message, or all mail for a given user, or for a given host, for example.

       The -l flag means 'literal', that is, treat all characters in the pattern as standing for themselves.  Otherwise the pattern must be a Perl
       regular expression.  The pattern match is case-insensitive.  If no file names are given on the command line, the standard input is read.

       If the location of a zcat command is known from the definition of ZCAT_COMMAND in Local/Makefile, exigrep  automatically  passes  any  file
       whose name ends in COMPRESS_SUFFIX through zcat as it searches it.

BUGS

       This manual page needs a major re-work. If somebody knows better groff than us and has more experience in writing manual pages, any patches
       would be greatly appreciated.
