Hi Fernando,
The mail from Matias really says it all, it's the extra `(POSIX regular
expressions)' which is screwing up the integer comparison `if test "..."
-ge 429; then'.
This seems like a bug in either:
less -V giving too much information for xz
- or -
xzless assuming that less -V is a certain way
For a quick (untested) hack, you could remove the check or change the
statement to:
if test "$(less -V | { read ver && echo ${ver#less }; } | awk '{print
$1}')" -ge 429; then
I'm sure others on this list will be able to give much better answers.
It's probably good to file a bug with the relevant upstream in any case.
Hope that helps,
Thanks,
Michael
