Just to add my 0.02c worth:
Make use of indenting in script writing!!! It makes maintenance on your script just SOOO much easier.
Trying to find a nested elif command in amongst all you "echo"'s was quite something:
#!/bin/sh
#
# Set local variables
USER=`/usr/bin/whoami`
ACCOUNT=Compaq
HOSTNAME=`/usr/bin/hostname`
DATE=`/usr/bin/date "+%Y%m%d"`
TEMP=`find . -name "gem*" | wc -l`
TEMPALL=`find . | wc -l`
# Purge old Log Files
#find /users/agaff/nospace/logs/ -name "*.txt" -atime +1|xargs rm -f
# Main Screen
clear
echo "<1> Delete GEM log files on host: " $HOSTNAME
echo "<2> Delete ALL Files in the /var/tmp ( maintenance only ) "
echo "<3> Exit - no files to be deleted"
echo ""
echo " Enter 1 or 2 or 3"
read ANSWER
if [ $ANSWER -eq "1" ]; then
clear
echo "Examining Log Files for host: " $HOSTNAME
echo ""
if [ $TEMP -eq "0" ]; then #(this is where it bombs out)
echo
echo
echo "*******************************************"
echo "There are no log files to be deleted from host:" $HOSTNAME
echo
elif [ $TEMP -gt "0" ];
then
echo "****************************************"
echo "There are " $TEMP "log files that can be deleted from host:"
$HOSTNAME
echo ""
echo ""
echo "<1> Delete GEM log files on Host" $HOSTNAME "in the /var/tmp directory"
echo "<2> Exit - no files to be deleted"
echo ""
echo " Enter 1 or 2"
echo""
read ANS1
if [ $ANS1 -eq "1" ]; then
clear
echo ""
echo ""
echo "Deleting GEM Logfiles Log Files"
#mkdir -p /users/agaff/nospace/logs/
#find /var/tmp/ -name "gem*" -atime +3 > /users/agaff/nospace/logs/$DATE"-"$HOST
NAME"-logs".txt| xargs -f >/dev/null 2>&1
echo ""
echo "*******************************************"
echo "Tmp Logs are now deleted and logfile updated"
echo ""
echo ""
elif [ $ANS1 -eq "2" ]; then
echo "Exiting"
else
echo "Invalid selection, exiting..."

Hi guys,
I'm trying to loop through a number of files that is set by whatever is in a field.

I thought simple, count the number of fields in the field and then loop... (1 Reply)

script
SCRIPT(1) BSD General Commands Manual SCRIPT(1)
NAME
script -- make typescript of terminal session
SYNOPSIS
script [-adfpqr] [-c command] [file]
DESCRIPTION
script makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an interactive
session as proof of an assignment, as the typescript file can be printed out later with lpr(1).
If the argument file is given, script saves all dialogue in file. If no file name is given, the typescript is saved in the file typescript.
Option:
-a Append the output to file or typescript, retaining the prior contents.
-c command
Run the named command instead of the shell. Useful for capturing the output of a program that behaves differently when associated
with a tty.
-d When playing back a session with the -p flag, don't sleep between records when playing back a timestamped session.
-f Flush output after each write. This is useful for watching the script output in real time.
-p Play back a session recorded with the -r flag in real time.
-q Be quiet, and don't output started and ended lines.
-r Record a session with input, output, and timestamping.
The script ends when the forked shell exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-d (if ignoreeof is not
set) for the C-shell, csh(1)).
Certain interactive commands, such as vi(1), create garbage in the typescript file. script works best with commands that do not manipulate
the screen, the results are meant to emulate a hardcopy terminal.
ENVIRONMENT
The following environment variable is used by script:
SHELL If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not set, the Bourne shell is assumed. (Most
shells set this variable automatically).
SEE ALSO
csh(1) (for the history mechanism).
HISTORY
The script command appeared in 3.0BSD.
BUGS
script places everything in the log file, including linefeeds and backspaces. This is not what the naive user expects.
