Hi everyone,

I'm trying to write a bash script which will cd into each directory in
the current one; do something; then cd back out again. The problem I
have is that some of the client's directories contain spaces.

My best effort is below.

function myecho {
echo $1
}

find ./*/ -maxdepth 0 -type d -print0 -exec echo {} \;
find ./*/ -maxdepth 0 -type d -print0 -exec myecho {} \;

With "echo" everything runs fine, but "myecho" gives multiple "No such
file or directory" errors. Can anyone give some advice?

Eventually I would replace myecho with something like doit:

function doit {
cd $1/src
make
cd -
}

You can't directly call a function in a -exec action, becuase it can't be
exec()ed.

So you can do something like

find ... -exec sh -c 'do your stuff with "$1" here' sh {} \;

quotes are important.

First quote your variables (e.g. so $1 becomes "$1") then get back to us if you
still have a problem. ALWAYS quote your variables unless you have a specific
reason not to.

Ok, thanks. I tried:
find ./*/ -maxdepth 0 -type d -print0 -exec sh -c myecho sh {} \;
but I get the error
sh: myecho: command not found

I have tried it with "$1" but I get the same error messages. I will
leave it as "$1" for now, thanks.
