AIX Shell Script Question

Cpare · 06-19-2015, 11:03 AM

The script below is failing with the addition of ${arrUsers[i]} to the echo line, if I change this to ${arrUsers[1]} it works, but I need the variable - I also tried ${arrUsers[$i]} without success. This worked in a prior script I wrote, but it may have been an older version of AIX - is there a new/better approach?

For those that will ask - this tool will search through directories to find content owned by users that are scheduled to have their AIX account removed, chowning the item (directory / folder) to a generic ID and make the file available to all users in a group.

Code:

#!/usr/bin/ksh

set -A arrFolders /dir2 /dir1
set -A arrUsers User1 User2

############################################################################

if [ "$1" = "" ]
then
   echo USAGE:
   echo "   usercleanup.sh OldUser"
else
        # Loop through each RootFolder
        for i in ${arrFolders[@]}
        do
                echo "Searching $i for $1 and chowning to ${arrUsers[i]}"
                #find . -user $1 \( -exec echo {} \; -o -exec true \; \) -exec grep banana {} \;
                #find $i -user $1 -exec chown ${arrUsers[i]} {} \; -exec chmod 766{} \;

        done
fi

Here is a little example that might help:

Code:

#!/bin/ksh

set -A arrFolders /dir2 /dir1
set -A arrUsers User1 User2

N="${#arrFolders[@]}"
MAX=$(expr $N - 1)

for i in $(seq 0 $MAX); do
    printf 'd: "%s" vs "%s"\n' "$i" "${arrFolders[$i]}" "${arrUsers[$i]}"
done

@NevemTeve - thanks for the assist, it's exactly what I needed - arrFolders wasn't an INT that could be used to locate the member in the other array, but the value of the array item (which explains why the echo line was showing the name). I used your approach and got the number of array values, then looped through them.

This is a script that I am trying to use to monitor CPU and memory utilization in my server.

#!/bin/ksh

# --- Environment --- #
SERVER=$(uname -n)
MAILTO=[AIXMonitoringReports@ferc.gov]

# --- High Water Marks --- #
typeset -i CPUHWM=60
typeset -i PAGHWM=60
typeset -i TMHWM=60

# --- Vars --- #
typeset -i CPU PAG TM

CPU=$(vmstat 1 1 | tail -1 | awk '{print $14+$15}')
[ $CPU -gt $CPUHWM ] && echo "CPU exceeded $CPU us+sy percent on $SERVER" | mailx -s "CPU alert for $SERVER (${CPU})" $MAILTO

PAG=$(vmstat 1 1 | tail -1 | awk '{print $6+$7}')
[ $PAG -gt $PAGHWM ] && echo "PAGING exceeded $PAG pi+po pages on $SERVER" | mailx -s "Paging alert for $SERVER (${PAG}/s)" $MAILTO

for DISK in $(lspv | awk '{print $1}')
do
TM=$(iostat -d $DISK 1 1 | grep hdisk | awk '{print $2}')
[ $TM -gt $TMHWM ] && echo "Disk $DISK exceeded ${TM}% tm_act on $SERVER" | mailx -s "DiskIO alert for $SERVER ($DISK ${TM}%)" $MAILTO
done

exit

I fail to see how it is related to the topic, but if it is, please use [code] and [/code] tags when you paste code. Also paste the actual code, not only the error message.
