(Gnu) sed command to change a matching part of a line
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
Is there a way in (Gnu) sed
to replace all characters in a matching part of a string? For example I might have a list of file paths with several (arbitrary number of) paths in each line, e.g.:
/a/b/c/d/e /f/g/XXX/h/i /j/k/l/m
/n/o/p /q/r/s/t/u /v/x/x/y
/z/XXX/a/b /c/d/e/f
I would like to replace all the slashes in paths containing XXX keping all the others untouched, e.g.:
/a/b/c/d/e #f#g#XXX#h#i /j/k/l/m
/n/o/p /q/r/s/t/u /v/x/x/y
#z#XXX#a#b /c/d/e/f
Unfortunately I cannot come up with a solution. Maybe it's even impossible with sed
. But I'm curious if somebody find a way to solve the problem.

We can replace any /
preceding XXX
with no intervening spaces like this:
# Using extended regex syntax
s!/([^ ]*XXX)!#1!
It's a very similar substitution for those that follow XXX
.
Putting them together in a loop makes this program:
#!/bin/sed -rf
:loop
s!/([^ ]*XXX)!#1!
s!(XXX[^ ]*)/!1#!
tloop
Output:
/a/b/c/d/e #f#g#XXX#h#i /j/k/l/m
/n/o/p /q/r/s/t/u /v/x/x/y
#z#XXX#a#b /c/d/e/f
That said, it might be simpler to use a pipeline, to break the file paths into individual lines and then reassemble them after the substitution:
sed -e 's/ *$//;s/ */&n/g'
| sed -e '/XXX/y,/,#,'
| sed -e ':a;/ $/{N;s/n//;ba}'
These are interesting solutions that work for me that way. Thank you.
