asked on
execute command recursively in subdirs
How can I rename alle files named "*.x" to "*.y" in all subdirs?
I'm looking for a general solution!
I know mmv - but I don't know, if I could use it here.
a solution would be a command that executes the same command in every subdir ...
so I would call:
run_rec mmv "*.x" "#1.y"
thanks

well, this is exactly, what I do all the time - but there must exist some better solution - more related to recursivity!!!

KISS - keep it small and simple
why do you warry about the find command? It does exactly what you asked for, not more and not less, exactly.
This with just a few key hits, if you do it recursively you need a script/program with a few hundred bytes. Why?
Find still is recursively, somehow.
An d with a simple -type f you can restrict to files. What do you need more?

I know what you mean - but there MUST exist something without "find -exec" or "xargs"!
nevertheless your command-line wouldn't work (the pwd doesn't change) :-)
thanks

> .. MUST exist ..
well, replace find by
ls -lR
but it's slower, not as flexible etc. etc.
Still do not understand why you need to make things more complicated.
> .. your command-line wouldn't work ..
which did not work?
what did not work?
what is the problem?
both work for me since years, 1'st one only if there is a basename, 2'nd on any UNIX I've ever seen
Keep in mind, that depending on your shell you need to quote parameters and/or escape some special charactzers.
> ..(the pwd doesn't change)
true. Why should it change? There is no reason for it (it just wastes time, or think of directories which a links:)
I gave you 2 perfect solutions to your question, either accept them or give a detailled description with example what you want to do.

ok - why the first line doesn't work:
"basename" is the name without directory.
so the "mv"-command can't work, because it won't find a file with this name in the current directory (because it is in a subdir!)!
and why I don't like it:
xargs is sooo slow, if you have a lot of (and I mean A LOT OF) files!!!
thanks though

agree, basename is not for recursive use, sorry didn't test again.
Did you try my 2'nd example? Probably, depending on shell and/or sed version, needs to be changed to:
find ./ -name \*.x | sed -e 's#\(.*\)\.x#mv & \1.y#'|sh

This may be easier to understand - always works for me
find -name "*.x" | sed -n -e 's/^\(.*\)\.x$/\1/p' | awk '{print "mv -f " $0 ".x " $0 ".y"}' | sh -x

find -name "*.x" | sed -n -e 's/^\(.*\)\.x$/\1/p' | awk '{print "mv -f " $0 ".x " $0 ".y"}' | sh -x

First of all: thanks to all your comments!
BUT:
these solution are all specific ones - the same I use today!!
(as you can read in my question) I'm looking for a *general solution* to do something like:
run_rec command -options parameters
thanks again
