is there any easy way to make our sed do the same as gnu sed here?
for now I have encapsulated the whole thing in a subshell
[backup@banshee ~]$ echo -n $(echo -n "/boot:7:1:5; /:7:1:5;
/var:7:1:5" | sed -n 's/[[:space:]]*;[[:space:]]*/;/gp')
/boot:7:1:5;/:7:1:5;/var:7:1:5[backup@banshee ~]$
Which works but seems a little hackish.
You can do it with awk(1):
# echo -n "/boot:7:1:5; /:7:1:5; /var:7:1:5" | \
awk ' { gsub("[[:space:]]*;[[:space:]]*", ";", $0) ; printf "%s", $0 }'
Not sure if that's any better than your solution using echo though.
Also trivial in perl(1) or python(1) or whatever, but it seems a waste
to fire up a whole perl interpreter just to do that.
Cheers,
Matthew
