ok thanks that worked..

now i am trying to get some numbers from a .txt file and put them into an array but when i try to echo it i get blank lines...

#!/bin/bash
array=(20 20 20 20 20)
j=0
while [ $j -lt 5 ]
do
awk '/%/' /cygdrive/c/unix/bin.txt | awk '{print $5}'> $[collectbininfo[j]]
echo ${collectbininfo[j]}
echo "$j"
j=`expr $j + 1`
done

bin.txt is the file from which i am picking out the numbers and the line which has the numbers has a % sign.. the file looks like this:

[1] Continuity 32 56%
[2] Continuity 32 56%
[3] Continuity 32 56%
[4] Continuity 32 56%
[5] Continuity 32 56%

i want to put all the 32's in an array

i already used the tr command on the bin.txt file to remove the CR's
thanks for your help guys.. i am still learning unix shell programming..

getusershell(3C)					   Standard C Library Functions 					  getusershell(3C)

NAME
getusershell, setusershell, endusershell - get legal user shells SYNOPSIS
#include <unistd.h> char *getusershell(void); void setusershell(void); void endusershell(void); DESCRIPTION
The getusershell() function returns a pointer to a legal user shell as defined by the system manager in the file /etc/shells. If /etc/shells does not exist, the following locations of the standard system shells are used in its place: /bin/bash /bin/csh /bin/jsh /bin/ksh /bin/ksh93 /bin/pfcsh /bin/pfksh /bin/pfsh /bin/sh /bin/tcsh /bin/zsh /sbin/jsh /sbin/pfsh /sbin/sh /usr/bin/bash /usr/bin/csh /usr/bin/jsh /usr/bin/ksh /usr/bin/ksh93 /usr/bin/pfcsh /usr/bin/pfksh /usr/bin/pfsh /usr/bin/sh /usr/bin/tcsh /usr/bin/zsh /usr/sfw/bin/zsh /usr/xpg4/bin/sh The getusershell() function opens the file /etc/shells, if it exists, and returns the next entry in the list of shells. The setusershell() function rewinds the file or the list. The endusershell() function closes the file, frees any memory used by getusershell() and setusershell(), and rewinds the file /etc/shells. RETURN VALUES
The getusershell() function returns a null pointer on EOF. BUGS
All information is contained in memory that may be freed with a call to endusershell(), so it must be copied if it is to be saved. NOTES
Restricted shells should not be listed in /etc/shells. SunOS 5.11 1 Nov 2007 getusershell(3C)
