How can I store a number in a variable in a shell script?
Support I have a script:
ls -la | wc -l > $TOTAL
echo "Total count is: $TOTAL"
This script is not giving me the desired output. Though I can use:
echo "Total count is: `cat $TOTAL`"
But is this a good way? Can't I directly store the numerical value of command ls -la | wc -l into variable $TOTAL, so I need not to do a "cat" this variable while echo it. I just wanna use:
echo "Total count is: $TOTAL", and I want that it give me output as:
Total count is: 35 (35 is just any number)
So question is how to store a numerical value in a variable?
You'll need to show us the exact error msgs.
You may be using a different shell; on Linux the default is bash.
#This next line shows what the parser is doing
at the top of your script.
Check the location of bash or ksh using
Whenever, I use this expression in Solaris, either as root (shell is /sbin/sh) or as my user i.e. jack (shell is /bin/bash), in both cases it throws error-
<scriptname>: syntax error at line 4:`TOTAL=$' unexpected
So how can I get rid of this?
