Intermittent problem reading from an input file.
First of all thanks to all for the good post, and the great site. I'm a noob, but I've been able to learna a lot by checking past posts.

I haven't been able to make sense of a problem that I've been working on for a while, hopefully someone can help me out. The script I wrote telnets into several routers via an expect script to check the numbers of CDP and EIGRP neighbors on each switch. The input file includes a list of the routers, the number of neighbors that should be seen and the number of problems since a successful run. Here's a sample of the source file:

Code:
 
#Input file for the department network script. Each router is checked
#for the following IP addresses as Eigrp neighbors and CDP neighbors:
#10.240.*.* , 10.241.*.* , 10.243.*.* , 10.244.*.* , 172.16.*.*
#192.168.*.* , 0.0.0.0
#The format for adding new entries is:
#Router Name, total Neigbors, problem count (0)
#agpcat1 1 0
agccat1 6 0
agpcat 6 0
anncat1 5 0


The first portion of the script ignores any line with # to start then reads the router name into a variable and sends that along with some predefined password stuff to an expect script. The output of the expect script is redirected to a file with the same name as the router. Later in the script I grep through each file looking for lines with IP addreses and count the number of lines to verify that it's the same as what's in the input file.

I run the script via cron every 5 minutes. The whole script works perfectly 99% of the time, but once or twice a day it doens't seem to parse the file normally. It seems to be including at least part of the first lines that are to be commented out and then it also misses part of the routers names. For instance I'll see a text file in the directory named 0.0.txt and ccat1.txt, when the 0.0.0.0 par of the input file should be skipped entirely and the ccat1.txt should be agccat1.txt.

Here's the first part of my script that seems to be causing me trouble. Any help you can give would be greatly appreciated.

Code:
 
#!/bin/ksh
C="/apps/scripts/Test/"
cd $C
b="username"
c="password"
d="enablepassword"
ulimit -nS 1024
 
while read ROUTER EIGRPNEI PROBLEMCOUNT
do
    if [[ "$ROUTER" != *#* ]] ; then
        ${C}report.exp $ROUTER $b $c $d > ${C}${ROUTER}.txt 2>/dev/null &
    fi
done < ${C}sourcefile
wait

merge_fonts

merge_fonts(3alleg4)						  Allegro manual					      merge_fonts(3alleg4)

NAME

       merge_fonts - Merges two fonts into one font. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       FONT *merge_fonts(FONT *f1, FONT *f2)

DESCRIPTION

       This function merges the character ranges from two fonts and returns a new font containing all characters in the old fonts. In general, you
       cannot merge fonts of different types (eg, TrueType fonts and bitmapped fonts), but as a special case, this function can  promote  a  mono-
       chrome bitmapped font to a color font and merge those. Example:

	  FONT *myfont;
	  FONT *myfancy_font;
	  FONT *lower_range;
	  FONT *upper_range;
	  FONT *capitals;
	  FONT *combined_font;
	  FONT *tempfont;
	  ...
	  /* Create a font that contains the capitals from  */
	  /* the fancy font but other characters from myfont */
	  lower_range = extract_font_range(myfont, -1, 'A'-1);
	  upper_range = extract_font_range(myfont, 'Z'+1, -1);
	  capitals = extract_font_range(myfancy_font, 'A', 'Z');

	  tempfont = merge_fonts(lower_range, capitals);
	  combined_font = merge_fonts(tempfont, upper_range);

	  /* Clean up temporary fonts */
	  destroy_font(lower_range);
	  destroy_font(upper_range);
	  destroy_font(capitals);
	  destroy_font(tempfont);

RETURN VALUE

       Returns a pointer to the new font or NULL on error. Remember that you are responsible for destroying the font when you are finished with it
       to avoid memory leaks.
