Machine Type: i386-redhat-linux-gnu
Bash Version: 2.05b
Patch Level: 0
Release Status: release
Description:
The DEL character is mishandled in double-quoted strings.
In the example below, the error happens in the line: T2="a $DEL".
Old BSD and System V shells work correctly. The bash manpage says:
Enclosing characters in double quotes preserves the literal
value of all characters within the quotes, with the exception
of $, `, and \.
So this doesn't seem to be a feature. :)
Repeat-By:
#!/bin/sh
DEL=`awk 'END{printf("%c", 0+127)}' </dev/null`
T1=a\ $DEL
T2="a $DEL"
set x `echo $T1|wc -c` `echo $T2|wc -c`; shift
L1=$1; L2=$2
case "$L1/$L2" in
4/4) echo shell ok;;
*) echo shell bug: L1=$L1, L2=$L2;;
