weird output
 

I had a similar script in solaris and it had no problem. I wrote this one in freeBSD and it gave me strange output. Can anyone please tell me why? thanks a lot

#!/bin/sh

#This is a shell script that checks file system capacity mounted on /home directory

#If file system is over 90% capacity, this shell script will generate notification emails sending to all users



warning()

{

 fs=$1          # first argument is the file system name

 fscap=$2       # second argument is the file system's capacity



 for user in `ls /home`



 do

   echo "File system mounted on /home directory is over 90% capacity. Please be ready for system maintainance. " | mail -s "Warning! $fs here is at $fscap capacity" user



 done



 echo "Warning: $fs is at $fscap capacity"

}



daOslg= `df -h | sed -n '/home/p' | tr -s ' ' ' ' | cut -d' ' -f1`

daOslgCap= `df -h | sed -n '/home/p' | tr -s ' ' ' ' | cut -d' ' -f5`



if ["$daOslgCap" -gt "90%"]

then

   warning $daOslg $daOslgCap

fi

output:

      

$ ./capChecker

./capChecker: /dev/da0s1g: Permission denied           

0%: not found

[: missing ]

Re: weird output
 

Hey there,

I think definitely you'll see some differences in performance. Solaris' sh is the bourne shell and a lot of linux/bsd distro's just like sh to bash or another shell.

The one thing I saw that jumped out at me was:

if ["$daOslgCap" -gt "90%"]

there may be 2 issues with this. Try padding spaces in between the [] and, possibly, check and see if there's an issue with the sense of your "if check", since "90%" is an alpha value and -gt is a unary comparison operator.

to add the spaces:
for the other part, you should clip the % from your value so you'll be checking if Hope that helps you get closer to an answer, if it doesn't answer the whole thing. If you could post the output of :

that might shed some more light.

Best wishes,

Mike
