linux - list/find all regular files in all subdirectories excluding binary files
2014-07
In Linux.
I know I can do find . -type f
, but that includes binary file and I couldn't find a way to exclude them with find
file /usr/bin/file
, for example, does not include the word "binary" in its output on my system. If file -i
is available, it does include the word "binary". Without -i
, it may be more reliable to test for the presence of the word "text".
find -type f -exec sh -c "file {} | grep text >/dev/null" \; -print
or
find -type f -exec sh -c "file {} | grep text >/dev/null" \; -ls
Using -i
:
find -type f -exec sh -c "file -i {} | grep -v binary >/dev/null" \; -print
Using file
is only going to be an approximation since it's using heuristics to determine the type of file and there's no hard-and-fast definition of what constitutes a "binary" file. Is an empty file "binary"? file
says it is. Also, there are lots of (normally uncommon) ways to trigger false positive IDs by file
.
Another way would be to exclude all files which have execute permission set for either user, group or others:
find . -type f ! -perm /u=x,g=x,o=x
(If binary equals execute permissions...)
show all files without executable permissions (although this is not specifically binary, so it may not be exactly what you need):
ls -l | awk '{if ($1 !~ /x/) print $8}'
find . -type f -exec file "{}" | grep -vE "ELF|archive"
How can I remove all .swp files in all of my subdirectories under Linux?
Remove all *.swp files underneath the current directory, use the find
command in one of the following forms:
find . -name \*.swp -type f -delete
The-delete
option means find will directly delete the matching files. This is the best match to OP's actual question.
Using-type f
means find will only process files.find . -name \*.swp -type f -exec rm -f {} \;
find . -name \*.swp -type f -exec rm -f {} +
Option-exec
allows find to execute an arbitrary command per file. The first variant will run the command once per file, and the second will run as few commands as possible by replacing{}
with as many parameters as possible.find . -name \*.swp -type f -print0 | xargs -0 rm -f
Piping the output toxargs
is used form more complex per-file commands than is possible with-exec
. The option-print0
tellsfind
to separate matches with ASCII NULL instead of a newline, and-0
tellsxargs
to expect NULL-separated input. This makes the pipe construct safe for filenames containing whitespace.
See man find
for more details and examples.
find . -name '*.swp' -delete
Having find do the delete itself remove any risk for space embedded in filename, ...
For extra security also consider adding -type f
for files only.
find /path -type f -name "*.swp" -delete
find /path -type f -name "*.swp" -exec rm -f "{}" +;
bash 4.0
shopt -s globstar
rm -f /path/**/*.swp
