[vdr] Re: OT: Shell script

[Karsten Müller <kmu@ratio.de>]

If you want your script to treat blanks and "bad characters" as every
other character you also could do something like this:

Script1.sh:
=================================================
#!/bin/bash
OFS=${IFS}
# ! The next 2 lines *must* be left as are !
IFS='
'
SRC="foo bar yugga yugga"

# Variable $SRC has the complete string (including) "bad" characters
echo $SRC >out1.txt
script2 $SRC

# restore file separator
IFS=${OFS}
~ ...more script statements... ~



Script2.sh:
=================================================
#!/bin/sh

OFS=${IFS}
# ! The next 2 lines *must* be left as are !
IFS='
'
echo $1 > out2.txt

# restore file separator
IFS=${OFS}
~ ...more script statements... ~


@Thomas Keil:

Single quotes (') won't be a good idea, because in upper example you'd
actually pass the string "$SRC" to the second script and not, as
intended, the content of $SRC :)
