Shell Programming and Scripting

#!/bin/bash
# Disk Space Monitoring for more than 95 %
# and Sending Alerts by Mail


if [ df -k |awk '$5 > 95 ];

then

`df -k |awk '$5 > 95 {print $1 " ----------- " $5}' |mailx -s "More than 95% disk usage in DEV" email@test.com';

else

exit 0

fi


I get the below error:
================
bash-3.00$ ./disk_usage_mail_alert-sriram.sh
./disk_usage_mail_alert-sriram.sh: line 14: syntax error near unexpected token `else'
./disk_usage_mail_alert-sriram.sh: line 14: `else '

that's very kludgy. the usage of awk is more than meets the eye
try this

Code:

df -k | awk 'int($5) > 95{ 
  subject = $1 " More than 95% disk usage "
  email = "email@test.com"
  cmd = "mailx -s \"" subject "\" " email
  cmd  | getline #or system(cmd)
  }
'

Can you suggest what is the syntax I am missing ?

bash-2.03$ ./new.sh
awk: syntax error near line 5
awk: illegal statement near line 5
./new.sh: line 8: 11058 Broken Pipe df -k
11059 Exit 2 | awk 'int($5) > 95{
subject = $1 " More than 95% disk usage "
email = "email@test.com"
cmd = "mailx -s \"" subject "\" " email
cmd | getline #or system(cmd)
}
'

====================================
bash-2.03$ cat new.sh (the script)
====================================
1
2 df -k | awk 'int($5) > 95{
3 subject = $1 " More than 95% disk usage "
4 email = "email@test.com"
5 cmd = "mailx -s \"" subject "\" " email
6 cmd | getline #or system(cmd)
7 }
8 '
====================================
bash-2.03$

modified the original.....

thanks, its good practice to close that. However, for my version of awk (GNU) , the "if" part, i don't think its needed cause i tested it. i think it differs across versions

oooops, my bad - I didn't see clearly what you're doing - sorry 'bout that:

Code:

df -k | awk 'int($5) > 95 { 
  subject = $1 " More than 95% disk usage "
  email = "email@test.com"
  cmd = "mailx -s \"" subject "\" " email
  cmd  | getline #or system(cmd)
  close(cmd)
  }
'

for the OP benefit.... if you're under Solaris - use 'nawk' instead of 'awk'.

And once again - sorry for the confusion!

no worries..
