Package: bash
Version: 2.05b-26
Severity: normal
Hi,
while trying to escape single quotes in a string, I discovered the following
behavior:
$ x="a'b'c"; echo "${x//\'/\'}"
a\'b\'c
When I leave off the last escaping backslash, the command line parser thinks
the line isn't complete:
$ x="a'b'c"; echo "${x//\'/'}"
>
Entering '}" there gives:
a'}"
'b'}"
'c
So, trying two quotes instead:
$ x="a'b'c"; echo "${x//\'/''}"
a''b''c
I haven't found a method to substitute a pattern with a single quote (not
using external commands of course).
I get the identical behavior if I do ${param/patt/str} instead of
${param//patt/str} and also with Etch's version of batch (reportbug's
info snippet added below the Sarge version's).
The behavior I *expected* is the following:
$ x="a'b'c"; echo "${x//\'/\'\\\'\'}"
a'\''b'\''c
Greetings,
Mike Dornberger
