Array with special Characters

donaldfung · #1 (**permalink**) 06-06-2008

Hi,

I would write a shell script to execute a series of command. However, if the cmd contains "-" in the array. It fails to do so.

I'd tried use ', " or \ but get the same result.

Quote:

#!/bin/bash

function checkConfig ()
{
for process in ${diskInfo[@]}
do
eval "${process}"
done
}

# Disk info details to be tar into tape
diskInfo=( 'df -k' "/sbin/fdisk -l" "cat /etc/fstab" )

checkConfig

Output:

Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda2 51605464 6134364 42849696 13% /
/dev/sda1 101086 17977 77890 19% /boot

./test.sh: line 31: -k: command not found

Usage: fdisk [-l] [-b SSZ] [-u] device
E.g.: fdisk /dev/hda (for the first IDE disk)
or: fdisk /dev/sdc (for the third SCSI disk)
or: fdisk /dev/eda (for the first PS/2 ESDI drive)
or: fdisk /dev/rd/c0d0 or: fdisk /dev/ida/c0d0 (for RAID devices)
...
./test.sh: line 31: -l: command not found

The following code snippet will show you how to extract the array contents

Code:

#!/usr/bin/bash

diskInfo=( 'df -k' "/sbin/fdisk -l" "cat /etc/fstab" )
num=${#diskInfo[@]}             # returns 3

for ((i = 0; i < $num; i++))
do
   echo ${diskInfo[$i]}
done
