I'm having a problem with perl *and* sed with a particular replace line. The lines I'm trying to search for, and replace, both have "/" characters, which is completely killing me.
line="password requisite /lib/security/$ISA/pam_cracklib.so retry=3"
newline="password required /lib/security/$ISA/pam_cracklib.so minlen=8 dcredit=-1
ucredit=-1 lcredit=0 minclass=3 retry=3"
I need to maintain whitespace, too.
perl -p -i -e s/"$line"/"$newline"/ file
That tosses out all kinds of errors, since perl believes the first "/lib" line to be the next delimiter. Even using the magical \Q and \E things doesn't work. AARRGGHH!!!
Sed seems to have the same problem. Anyone have any ideas on how I can get
this to work? And yes, unfortunately, I need to use the variables.
Thanks,
David
.) you should probably have quotes around the -e argument, as in:
perl -p -i -e "s/$line/$newline/" file
.) I'm not positive, but I believe that the character immediately after
the s becomes the separator, so you could use s|from|to| or s^from^to^
or whatever. Otherwise, simply use \ before the special character to
escape it from being interpreted as being special (iow, treat it literally).
