Question Struggling with arrays and delimited file
Hi,

I am trying to use arrays in my script but can not seem to get it to work.

I have a file called sections, this contains headers from a tripwire log file, separated by "@" but could be "," if easier
The headers will be used to cut sections from the log file into another to be mailed.

sections looks like this:
Code:
Section: Unix File System@Total violations found
Rule Name: System Boot Changes@Added object name:

I have taken the following snippet of code for test purposes but can not get it to work. I get [: 0: unary operator expected

Code:
#!/bin/bash

SPArraya=( "${SPArraya[@]}" 'awk -F'@' '{ print $1 }' sections')
SPArrayb=( "${SPArrayb[@]}" 'awk -F'@' '{ print $2 }' sections')

#Displaying the contents of the array
i=0
while [ $i -lt $len ]
 do
FIRSTLINE=${SPArraya[$i]}
LASTLINE=${SPArrayb[$i]}
i=$((i+1))
echo "Section" $i
echo "First line is: " ${SPArraya[$i]}
echo "Last line is: " ${SPArrayb[$i]}
done


Can someone please help.

catman

CATMAN(8)						    BSD System Manager's Manual 						 CATMAN(8)

NAME

     catman -- format cat pages from man pages

SYNOPSIS

     catman [-knpsw] [-m directory] [sections]
     catman [-knpsw] [-M directory] [sections]

DESCRIPTION

     catman creates formatted versions of the on-line manual pages from their nroff(1) source.	Manual pages whose formatted versions are missing
     or out of date are regenerated.  If manual pages are regenerated, catman also regenerates the whatis database.

     The optional sections argument is one word, and contains the section numbers of all the sections to be checked.  For example, if sections is
     ``13f8'', the manual pages in sections 1, 3f, and 8 will be checked and regenerated.  If no sections argument is provided, catman will try to
     operate on all of the known manual sections.

     The options are as follows:

     -k      Ignore errors from nroff when building manpages.

     -n      Do not create the whatis database.

     -p      Display the commands that would have been executed, but do not actually execute them.

     -s      Perform work silently; do not echo commands as they are executed.	This flag is ignored if -p is specified.

     -w      Only create the whatis database.

     -m directory
	     Add directory to the set of directories to be updated.

     -M directory
	     Update manual pages in directory.
