To begin with, here's the script (so far):<br></div><div><br></div><div><span style="font-family: Consolas; font-size: small;"><span style="font-family: Consolas; font-size: small;"><span style="font-size: 11pt;"></span></span></span><div style="padding-left: 30px;"><span style="color: #002060;">#!/bin/bash</span></div><span style="font-family: Consolas; font-size: small;"><span style="font-family: Consolas; font-size: small;"><span style="font-size: 11pt;"></span></span></span><div style="padding-left: 30px;"><span style="color: #002060;">set -x</span></div><span style="font-family: Consolas; font-size: small;"><span style="font-family: Consolas; font-size: small;"><span style="font-size: 11pt;"></span></span></span><div style="padding-left: 30px;"><span style="color: #002060;">for i in $(`df -hl | awk '{print $NF}' | grep -v ^\/dev`);</span></div><span style="font-family: Consolas; font-size: small;"><span style="font-family: Consolas; font-size: small;"><span style="font-size: 11pt;"></span></span></span><div style="padding-left: 30px;"><span style="color: #002060;">do</span></div><span style="font-family: Consolas; font-size: small;"><span style="font-family: Consolas; font-size: small;"><span style="font-size: 11pt;"></span></span></span><div style="padding-left: 30px;"><span style="color: #002060;"># find $i -path /proc -prune -o -type f -perm +6000 -ls >> /tmp/Test1_"$HOSTNAME".txt</span></div><span style="font-family: Consolas; font-size: small;"><span style="font-family: Consolas; font-size: small;"><span style="font-size: 11pt;"></span></span></span><div style="padding-left: 30px;"><span style="color: #002060;"> echo $i| rev ;</span></div><span style="font-family: Consolas; font-size: small;"><span style="font-family: Consolas; font-size: small;"><span style="font-size: 11pt;"></span></span></span><div style="padding-left: 30px;"><span style="color: #002060;">done</span></div><span style="font-family: Consolas; font-size: small;"><span style="font-family: Consolas; font-size: small;"><span style="font-size: 11pt;"></span></span></span><div><span style="color: #002060; font-family: Calibri;"> </span></div><div><span style="color: rgb(0, 0, 0); font-family: arial,helvetica,freesans,sans-serif;">I'll skip explaining the 1st two lines, since those are (probably) fairly obvious. The third line basically grabs a listing of *local* filesystems <em>(so that I don't waste 'time x # of servers' rescanning common shared mounts)</em> and assigns it (one line/filesystem at a time) to a variable.</span></div><div><span style="color: rgb(0, 0, 0); font-family: arial,helvetica,freesans,sans-serif;"><br></span></div><div><span style="color: rgb(0, 0, 0); font-family: arial,helvetica,freesans,sans-serif;">The variable is then used as the target filesystem within a find statement <em>(the intent is to keep from having to manually determine the local filesystems on each of the different servers)</em>. In the script above, that line is commented out because I was trying to determine whether that line was contributing to the problem I'm seeing. The following 'echo' line is just there to provide output to the screen so that I can see what, if anything is being generated. (So far, that line isn't producing anything.)<br></span></div><div><span style="color: rgb(0, 0, 0); font-family: arial,helvetica,freesans,sans-serif;"><br></span></div><div><span style="color: rgb(0, 0, 0); font-family: arial,helvetica,freesans,sans-serif;">Prior to adding the 'set -x' line for debugging, the only output that I received was the line '<span style="font-family: Consolas; font-size: small;"><span style="font-size: 11pt;"><span style="color: #1f497d;">forloop.sh: line 7: on: command not found</span></span></span>'. It *seems* apparent that it's somehow extracting the center two characters from the 'done' string in line 7, & trying to use that as a command - but I have no idea how/why it's doing that.<br></span></div><div><span style="color: rgb(0, 0, 0); font-family: arial,helvetica,freesans,sans-serif;"><br></span></div><div><span style="color: rgb(0, 0, 0); font-family: arial,helvetica,freesans,sans-serif;">After adding the 'set -x' line to the script, the output becomes:<br></span></div><div><span style="color: rgb(0, 0, 0); font-family: arial,helvetica,freesans,sans-serif;"><br></span></div><div><div style="padding-left: 30px;"><span style="color: #1f497d;">+++ df -hl</span></div><div style="padding-left: 30px;"><span style="color: #1f497d;">+++ awk '{print $NF}'</span></div><div style="padding-left: 30px;"><span style="color: #1f497d;">+++ grep -v '^/dev'</span></div><div style="padding-left: 30px;"><span style="color: #1f497d;">++ on / /boot /home /opt /var /prod/app/local /prod/app/shared</span></div><div style="padding-left: 30px;"><span style="color: #1f497d;">forloop.sh: line 7: on: command not found</span></div><div><span style="color: #1f497d;"><br></span></div><div><span style="color: #1f497d;"><span style="color: #000000; font-family: arial,helvetica,freesans,sans-serif;">Is anyone here able to explain why I'm seeing this behavior??
