NAME
notrail - remove all trailing spaces characters from text files
SYNOPSIS
notrail [-h(elp)] [-a(ll_whitespace)] [-f filelist] [-m max_filesize]
[-p(ipe)] [-q(uiet)] [-v(erbose)] file...
DESCRIPTION
notrail removes all trailing space characters from text files using
Python's rstrip() method.
OPTIONS
-h Print help and quit.
-a Remove all trailing whitespace characters (spaces, tabs, etc.)
instead of just spaces.
-f file_list
Read the names of files to be processed from the specified file.
-m max_filesize
Skip processing of files larger than the specified size to avoid
running out of RAM. The default value is 1073741824 bytes,
i.e., 1 GiB.
-p Read the names of files to be processed from stdin.
-q Quiet output. No output commentary will be printed.
-v Verbose output. Commentary about unchanged files will be
printed in addition to the normal commentary about changed
files.
EXAMPLES
Remove trailing spaces from a couple of files:
notrail file01.txt file02.txt
Remove trailing spaces from a large block of source code:
find . -name "*.c" -print0 | xargs -0 notrail
find . -name "*.h" -print0 | xargs -0 notrail
NOTES
If notrail appears to be malfunctioning, try running it in single-
threaded mode by using the -T 1 option. This permits more meaningful
error messages to be printed.
