Linux Reset $1 variable
Hi all,

I'm using a scipt with one input and one output.
I'm referring to the input by $1
after executing a command line, I'm getting the output via $1.
Normally, the $1 shouldn't get the same values between the first call and the second.
Is there a solution to force my second call for $1 to get the value of $PS -efo pcpu,vsz,arg

Here is my script:
Code:
SWAPINFO="/usr/sbin/swapinfo"
PS="/usr/bin/ps"
AWK="/usr/bin/awk"
GREP="/usr/bin/grep"
SORT="/usr/bin/sort"
TAIL="/usr/bin/tail"


MYPAT="$1"
Availability=0
export UNIX95=1
VAR=$($SWAPINFO -ta | $GREP memory | $AWK ' { print $2 } ')
MYCPU=` $PS -efo pcpu,vsz,args | $GREP -v COMMAND | $GREP -v awk | $GREP "$MYPAT" | $SORT -k 1 | $TAIL -1 | $AWK -v var=$VAR -v pattern="$MYPAT" ' { print $1 } '`
echo $MYCPU

shells

shells(4)							   File Formats 							 shells(4)

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The following default shells are used by utilities: /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/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, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list.

       Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1).
