Here is the idea:

I would like to create a function that will show only a part of the command df -h with sed.
The aim is to see only the disk name and the pourcentage of it. (eg"c0t0d0s0 / 70%")

In my full script I had the command and it's working well.
echo "toto" `df -h /|grep %| sed -e 's/[0-9].[0-9]G//g' -e 's/[0-9].[0-9]M//g' -e 's/[0-9]G//g' -e 's/[0-9]M//g' -e 's#/dev/dsk/#/#g'` "\n" >> $LOG &&

I would like to create a function that will take those command.

But I should have some mistakes Smilie in because i cannot make it work. Does someone have an idea? thank


Here is my script

#!/bin/ksh
#
DATE=`date '+%y%m%d%H%M'`
LOG=/var/log/autosed$DATE.log
export LOG
DEBUG=echo

#function that permit to sow a part of the df -h command.

call_sed()
{
sedcmd=`grep % | sed -e 's/[0-9].[0-9]G//g' -e 's/[0-9].[0-9]M//g' -e 's/[0-9]G//g' -e 's/[0-9]M//g' -e 's#/dev/dsk/#/#g'` >> $LOG
df -h $1 | $sedcmd
}
call_sed "/"

You are assigning the output of a command to $sedcmd instead of the command itself.

Don't make your script more complex than it need be:

Code:
call_sed()
{
  df -h $1 |
   grep % | sed -e 's/[0-9].[0-9]G//g' \
                -e 's/[0-9].[0-9]M//g' \
                -e 's/[0-9]G//g' \
                -e 's/[0-9]M//g' \
                -e 's#/dev/dsk/#/#g' >> "$LOG"
}
