Problem With Script

Shannon_1 — Thu, 25 Apr 2002 13:32:25 GMT

OK, I'm in the beginning stages of learning
how to script. I'm using the Bourne shell
and can't seem to get my variables to accept values other than strings.

Example:

#!/bin/sh
day='date+%a'
echo $day

Result: date+%a

What am I doing wrong?

Thanks.

You should be using 'backticks' the ` rather than the single quote '

The better answer is to use the POSIX shell convention
DAY=$(date '+%a')

There should be a space between date and +.
And make sure you are using the command substitution quotes.

day=`date +%a`
echo $day

Hi Shannon,
DAY=`date +%d`

few more variable initiliztion

HOSTNAME=`uname -n`
FILE="/usr/local/etc/filename"
RUNNING=`ps -e |grep sleep |wc -l`

system is down.
RESULT=`/etc/ping system1 64 3 | grep "packet loss" | sed 's/%//g' | awk '{print
$7}'`
if [ $RESULT -ge 100 ]; then
mailx -s "system1 is down `date`" sachin < /dev/null
exit
fi

arithmatic.
total_min=`expr ${SECONDS} / 60`

Shanon,

I would normally use:

#!/bin/sh
day=`date "+%a"`
echo $day

Thu

Thanks,
