Passing a regexp to grep via a shell script
Hello,

I have the output of ls -l stored in a text file called "files.txt".

-rwx------ 1 user1 dev 130 Sep 21 16:14 sc1.sh
-rwxr----- 1 user1 dev 10328 Sep 29 20:11 sc10.sh
-rwxr----- 1 user1 dev 9984 Sep 30 15:33 sc11.sh
-rwxr----- 1 user1 dev 9987 Oct 1 10:05 sc12.sh
-rwx------ 1 user1 dev 3215 Sep 21 17:15 sc2.sh
-rwx------ 1 user1 dev 3215 Sep 22 10:04 sc3.sh
-rwxr----- 1 user1 dev 2174 Sep 22 13:34 sc4.sh
-rwxr----- 1 user1 dev 2837 Sep 22 16:35 sc5.sh
-rwxr----- 1 user1 dev 5923 Sep 23 11:51 sc6.sh
-rwxr----- 1 user1 dev 5995 Sep 23 13:20 sc7.sh
-rwxr----- 1 user1 dev 6458 Sep 24 13:37 sc8.sh
-rwxr----- 1 user1 dev 8375 Sep 26 10:53 sc9.sh

I need to extract the filename and filesize, viz column 9 & 5 for all files matching a filename pattern into another file.

I have tried the following shell script.

set -f
FILE_EXT=*.sh
awk '{print $9" "$5}' files.txt | grep "$FILE_EXT"

It does not print the rows with the patterns. The pattern used for grep through the shell script needs to be configurable via the command line.

Can anybody help me with this.

Thanks.

mkdic

MKDIC(1)						      General Commands Manual							  MKDIC(1)

NAME

       mkdic - Tool for creating a user dictionary

SYNOPSIS

       mkdic [{-cs|-cannaserver} canna-server] [-s] [- | -l local-file] remote-dic

DESCRIPTION

       mkdic  creates  user dictionary named remote-dic in the user dictionary directory of the remote host, on which cannaserver(1M) is in opera-
       tion.  Dictionary file name remote-dic is assigned to this file at this time.

       If the - and -l option isn't specified, mkdic creates an empty dictionary.

       If the - option is specified, the standard input will be used as the dictionary file. If the -l option is  specified,  local-file  will	be
       used as the dictionary file.

       If the user dictionary directory does not exist, it will be created.

       Dictionary  directory  file  -- dics.dir -- is rewritten automatically after the registering. The registered dictionary can thus be used by
       writing the dictionary name into the customize file.

OPTIONS

       -cs canna-server (or -cannaserver canna-server)
		   Specifies the server machine that contains the dictionary to be created.

       -s	   Indicates that the dictionary to be created is an adjunct dictionary.  If this option is omitted, the dictionary will  be  cre-
		   ated as an independent-word one.

       -l local-file
		   Registers the input data from local-file.

       -	   The standard input will be used as the dictionary file.

EXAMPLES(1) If you want to creat an empty dictionary file:

	     % mkdic test(2) If you want to register the input data from the standard input:

	     % mkdic test -

       Registers  the  input data from the standard input, in the user dictionary directory under dictionary name ``test''.  The following line is
       then added to dictionary directory file -- dics.dir -- :

		 user1.t(.mwd) -test-(3) If the dictionary file is specified:

	     % mkdic test -l test1.t

       Registers independent-word dictionary file ``test1.t'' in the remote host's user dictionary directory under dictionary name ``test''.   The
       following line is then added to dics.dir:

		user1.t(.mvd) -test-

       user1.t is a dictionary file name generated automatically by the system.
