Is there a way to search and delete all executables files within folder if there is no extension?
e.g Let's suppose I have 4 files with .ubu extension and the following bash does the job I'm asking for:
rm *.ubu
e.g_2 Now let's suppose I have 4 but there is no extension at all, something like:
test test_2 test_3 (chmod +x on them)
How do I delete those files?
If we're talking about files with executable bit set, then find command has -executable test, and a -delete action.
find /DIR/EC/TORY -type f -executable -delete
or
find /DIR/EC/TORY -type f -executable -exec rm -f {} ;
should do the trick.
To specifically delete all executable files in your home directory (not in sub-directories) and ask you whether you want to delete each file you can do something like
find ~ -type f -executable -maxdepth 0 -exec rm -i {} ;
from man find:
-exec command ;
Execute command; true if 0 status is returned. All following
arguments to find are taken to be arguments to the command until
an argument consisting of `;' is encountered. The string `{}'
is replaced by the current file name being processed everywhere
it occurs in the arguments to the command, not just in arguments
where it is alone, as in some versions of find. Both of these
constructions might need to be escaped (with a `') or quoted to
protect them from expansion by the shell. See the EXAMPLES sec‐
tion for examples of the use of the -exec option. The specified
command is run once for each matched file. The command is exe‐
cuted in the starting directory. There are unavoidable secu‐
rity problems surrounding use of the -exec action; you should
use the -execdir option instead.
-exec command {} +
This variant of the -exec action runs the specified command on
the selected files, but the command line is built by appending
each selected file name at the end; the total number of invoca‐
tions of the command will be much less than the number of
matched files. The command line is built in much the same way
that xargs builds its command lines. Only one instance of `{}'
is allowed within the command. The command is executed in the
starting directory.
