# 8  
Old 07-22-2008
You do not need to use tr to check for digits. In most modern shells this sort of check can be done entirely within the shell. For example in ksh93, assuming the number of digits is between 6 and 8:
Code:
$ str="my_identifier8859574"
$ id=${str/@(my_identifier)+({6,8}(\d))/\2}
$ print $id
8859574
$ [[ $id1 != @({6,8}(\d)) ]] && print "ERROR"
$

cscope-indexer

cscope-indexer(1)					      General Commands Manual						 cscope-indexer(1)

NAME

       cscope-indexer - Script to index files for cscope

SYNOPSIS

       cscope-indexer [-v] [-f database_file] [-i list_file] [-l] [-r]

DESCRIPTION

       This  script  generates	a list of files to index (cscope.out), which is then (optionally) used to generate a cscope database.  You can use
       this script to just build a list of files, or it can be used to build a list and database.  This script is not used to just build  a  data-
       base (skipping the list of files step), as this can be simply done by just calling "cscope -b".

       Normally,  cscope will do its own indexing, but this script can be used to force indexing.  This is useful if you need to recurse into sub-
       directories, or have many files to index (you can run this script from a cron job, during the night).  It is especially	useful	for  large
       projects,  which  can  contstantly  have source files added and deleted; by using this script, the changing sources files are automatically
       handled.

       Currently, any paths containing "/CVS/" or "/RCS/" are stripped out (ignored).

OPTIONS

       -f database_file
	      Specifies the cscope database file (default: cscope.out).

       -i list_file
	      Specifies the name of the file into which the list of files to index is placed (default: cscope.files).

       -l     Suppress the generation/updating of the cscope database file.  Only a list of files is generated.

       -r     Recurse into subdirectories to locate files to index.  Without this option, only the current directory is searched.

       -v     Be verbose.  Output simple progress messages.
