Shell Programming and Scripting

Please paste your alias here and if possible your script which uses the alias.

Dear agn/all,

naresh@dev1#alias

alias cls='clear'
alias dir='ls -a'
alias utils='sh ~/scripts/utils.sh'

utils.sh

#!/bin/bash

TOP="/opt/sfw/bin/top"

$TOP | grep -i "Memory" | awk '{print $2" " $4}'| sed -e 's/M//g'| awk '{percent=(($1-$2)/$1)*100} { print "Memory Utilization="percent"%"}'

sar -u 1 | tail -1 | awk '{print "CPU Utilization="100-$5"%"}'


The Script in which i m using alias is 123.sh

utils
rm /data/naresh/ican.txt
rm /data/naresh/scripts/tomem
----------------------------------------------------------

# sh 123.sh

utils not found

Thanks & Regards
Naree

Why don`t u use vmstat for memory statistics?

Top is a dynamic page...this script doesnt work I guess

Or another alternative with free command

percentage=`free|grep "Mem:"|awk '{print $3/$2*100}'`

Dear All,

Thanks for u r replies. But please understand my problem. I want to use the alias name "utils" in a script called 123.sh

But that alias is not working. Please tell me how use the alias name in a script.

Thanks & Regards
Naree

NAree,

How you pretend for the alias to work when utils.sh include a line in the script which doesnt work? Test the utils with simpler examples. Remove TOP and SAR and test it with a simple command.

You will either have to source your .bashrc or .profile in your script or use 'sh -l' to run your script. '-l' is for login shell so that it reads your .bashrc.

Code:

$ cat 123.sh
#!/bin/sh -l

. .bashrc
utils
...

OR

Code:

$ cat 123.sh
#!/bin/sh -l
utils
..

OR

Code:

$ sh -l 123.sh
