Bash: find files with trailing spaces at the end of the lines

问题

I'm looking for a bash command to find files with trailing spaces at the end of each line. I'm not interested in removing the spaces, but just in finding the files.

回答1:

Find files that has trailing spaces.

find . -type f -exec egrep -l " +$" {} \;

回答2:

If the goal is to list files which have trailing whitespaces in one or more lines:

grep -r '[[:blank:]]$' .

To not print the lines, and print just the file names only, also specify the -l option. That's l as in the word list, not the number 1.

回答3:

Find files with one or more trailing space characters:

find . -name "*" | xargs egrep ".* +$"

回答4:

There is an option to list the files which do not contain a match anywhere in them; use that and a regex for a character other than a space just before end of line.

grep -L '[^ ]$' *

To recurse directories, add -r. To search for other whitespace characters as well, use a character class $'[^ \t]$' or the POSIX '[^[:blank:]]$' for the regex.

回答5:

Using ack (or ag):

ack -l ' \n'

Note: Like some of the other answers, this will list files that contain one or more lines with trailing spaces.

回答6:

If the goal is to list files with trailing whitespace in the current path:

grep -rli '[[:blank:]]$' .

回答7:

If the question is literally to find files that have a blank at the end of every single line, then this should work:

grep -rL '[^[:blank:]]$' .

The -L tells grep to report every file that does not match the pattern, and the pattern is looking for lines that do not have a blank immediately preceding the newline.

回答8:

Try this :

find . -type f -name "* "
