Right now the checks for the various scripting languages only match
specific filename extensions, 'sh' check only matches *.sh, 'python'
*.py, 'perl' *.{pl,pm}, etc. It would be good to scan all files for a
#! line and check those too.
This is on the TODO list. The plan is to use MIME types stuff but I
haven't been able to find a good way to do that on the command-line, if
you can think of a method for this, that would be nice.
For source code, we might use ack(1). For example, this prints names of
Python code:
ack -f --python --print0
... except that ack, unlike find, doesn't prefix filenames with "./". To
avoid argument injections, we'd have to add it manually:
ack -f --python --print0 | perl -0pe 's,\A,./,'
... which looks less attractive. :\
For binary files, I came up with this monster:
find . -type f -exec sh -c 'file -i --print0 "$1" | cut -d "" -f 2 | grep -q ": image/png;" &&
printf "%s\0" "$1"' sh {} \;
It's horrible enough that I'll probably write a new tool, so that you
can write:
find . -type f -print0 | mimegrep -0 image/png
