Top Forums UNIX for Dummies Questions & Answers grep to handle a 0 result Post 302105871 by ocelot on Monday 5th of February 2007 09:43:29 AM

I have tried grep -c but that doesnt work either, it keeps on dumping out.

The script is actually a TCL script with embedded UNIX commands. The part its failing on is like so:

set td [exec grep -c "InvalidMessage" $logdir/$t | wc -l]

(I have assigned the variables logdir and t from before)

and i run the script and this occurs:

child process exited abnormally
while executing
"exec grep -c "InvalidMessage" $logdir/$t | wc -l"


It happens because there are no "InvalidMessage" strings in the file, but I know this and want the result i.e. 0 to be assigned to td

NAME
parse_dynamic_clustertoc - parse clustertoc file based on dynamic entries SYNOPSIS
cdrom/export/exec/sparc.Solaris_2.x/sbin/install.d/parse_dynamic_clustertoc cdrom/export/exec/i386.Solaris_2.x/sbin/install.d/parse_dynamic_clustertoc DESCRIPTION
This script parses the clustertoc file before the suninstall(1M) process is run. parse_dynamic_clustertoc is called by a modified syscon- fig script on the install CD. When parse_dynamic_clustertoc runs, it reads the clustertoc and when it encounters SUNW_CSRMBRIFF lines, it either checks the platform using the script's builtin function, or calls an external script. The script exits with a 0 if the cluster entry is included, otherwise it will be ignored. If the cluster entry is to be included, the SUNW_CSRMBRIFF =(test test_arg)cluster line is converted to SUNW_CSRMEMBER =cluster. EXAMPLES
Example 1: Checking For an SX Framebuffer The following is an example of a simple external test to check for an SX Framebuffer. The entry in the clustertoc file is shown and fol- lowing that is the script that must be placed in the install.d/dynamic_test directory. SUNW_CSRMBRIFF=(smcc.dctoc sx)SUNWCsx #! /bin/sh # # Likewise, this file is expected to live under $(TESTDIR). # case "$1" in sx) prtconf -p | grep 'SUNW,sx' 1> /dev/null;; esac FILES
