executing commands in directories containing specific files

All,

I'd like to find TeX files (find $HOME -type f -name '*.tex'). Let's say i
have found files a.tex, b.tex, and c.tex. Now, i wanna remove a.aux, b.aux,
c.aux. What's the best way of doing that?

Cheers

find $HOME -type f -name '*.tex' -exec rm {} \;

That won't get the aux files

I would use

for f in $HOME/**/*.tex; do rm $f; rm ${f:r}.aux; done

Leonardo Barbosa sent me the following 0.3K:

There's probably a way to combine the glob and the expansion that I don't know about, but you could do this:

  texs=(*.tex) && rm ${^texs:r}.aux

${texs:r} strips off the extension giving the Root name of each element in texs. The ${...}.aux causes the .aux to be appended, and the ${^...} causes the appending to happen element-wise.

Oh, whoops. I missed the differing extensions. In that case your
solution is probably best, except without removing the tex files
themselves:

  for f in $HOME/**/*.tex; do rm ${f:r}.aux; done

I like using the (e) flag, but it's sometimes tricky to get right on the
first try because you have to be careful to match up the parens in the
reply=(...) assignment, the quotes around the expression, the outer set
of delimiters (I used [...] below) and the parens around the whole thing:

    rm **/*.tex(.e['reply=(${REPLY:r}.aux)'])

But you can also use colon-modifiers as glob qualifiers, so if the .tex
never appears anywhere but at the end:

    rm **/*.tex(.:s/.tex/.aux)

If you've already got the filenames, say, in an array:

    texi=( $(find $HOME -type f -name '*.tex') )

Colon-modifiers work on every word in an array, so you can use the "^"
flag (rcexpandparam) like so:

    rm ${^texi:r}.aux

Or you can just use one of the loops already suggested.

Why use find instead the glob way :
texi=( **/*.tex(.) )

When the result is use as a stream find is a beter way but to create an
array ?

All, thanks a lot. That worked!

Leonardo had a "find" command in his original question, so I just copied
it, in case he already had a working script that was producing the list
of .tex files and he only needed a new part to change the suffix.
