Set executable permissions only to executable files

If you make a mess (like I did) and you removed all the executable permissions of a directory (or you set executable permissions to everything) this can help.

It supports spaces and other special characters in the file paths, but it will work only in bash, GNU find and GNU egrep.

You can complement it with these two commands:

1. add executable permission to directories:

find . type d -print0 | xargs -0 chmod +x

2. and remove to files:

find . type d -print0 | xargs -0 chmod -x

Or, in the same loop:

while IFS= read -r -u3 -d $'\0' file; do case $(file "$file" | cut -f 2- -d :) in :*executable*|*ELF*|*directory*) chmod +x "$file" ;; *) chmod -x "$file" ;; esac || break done 3< <(find . -print0)

Check if the files in current directory has the RPATH variable defined

Using gentoo prefix portage I got in a situation where some packages did not contain the needed RPATH variable. This command helped me to find out which ones I should recompile

sed edit-in-place using -a option instead of -i option (no tmp file created)

does the -i option open a tmp file?

this method does not.

Renames all files in the current directory such that the new file contains no space characters.

This is a better version, as it does no command piping, uses for instead of while loops, which allows for a list of files in the current working directory to be natively processed. It also uses the -v/verbose option with mv to let you know what the command is doing.

While the command does exactly the same in a better way, I would modify the sed option to replace spaces with underscores instead, or dashes.

Please note that you'll receive errors with this command as it tries to rename files that don't even have spaces.

Use file(1) to view device information

file(1) can print details about certain devices in the /dev/ directory (block devices in this example). This helped me to know at a glance the location and revision of my bootloader, UUIDs, filesystem status, which partitions were primaries / logicals, etc.. without running several commands.
