If your sed version doesn't support the POSIX Character Classes you can use a space and a \t within the square brackets:

Code:
sed 's/[ \t]*$//'

Older versions of sed even doesn't recognize the \t as a tab. In that case you can type <Ctrl-V> <TAB> successively instead of \t:

Code:
sed 's/[     ]*$//'

NAME
inline-detox -- clean up filenames (stream-based) SYNOPSIS
inline-detox [-hnLrv] [-s -sequence] [-f -configfile] file ... DESCRIPTION
The inline-detox utility can remove spaces and other such annoyances from streams. It'll also translate or cleanup Latin-1 (ISO 8859-1) characters encoded in 8-bit ASCII, Unicode characters encoded in UTF-8, and CGI escaped characters. Basically its detox, but does not oper- ate on files. Sequences inline-detox is driven by a configurable series of filters, called a sequence. Sequences are covered in more detail in detoxrc(5) and are discoverable with the -L option. Some examples of default sequences are iso8859_1 and utf_8. Options The main options: -f configfile Use configfile instead of the default configuration files for loading translation sequences. No other config file will be parsed. -h --help Display helpful information. -L List the currently available sequences. When paired with -v this option shows what filters are used in each sequence and any properties applied to the filters. -r Recurse into subdirectories. -s sequence Use sequence instead of default. -v Be verbose about which files are being renamed. -V Show the current version of inline-detox. Deprecated Options Deprecated Options are options that were available in earlier versions of inline-detox but have lost their meaning and are being phased out. --remove-trailing Removes _ and - after .'s in filenames. This was first provided in the 0.9 series of inline-detox. After the introduction of sequences, it lost its meaning, as you could now determine the properties of wipeup through a particular sequence's configura- tion. It presently forces all instances of the wipeup filter to use remove trailing, regardless of what's actually in the config files. FILES
detoxrc The system-wide detoxrc file. ~/.detoxrc A user's personal detoxrc. Normally it extends the system-wide detoxrc, unless -f has been specified, in which case, it is ignored. iso8859_1.tbl The default ISO 8859-1 translation table. unicode.tbl The default Unicode (UTF-8) translation table. EXAMPLES
echo Foo Bar | inline-detox -s iso8859_1 -v Will run the sequence iso8859_1 listing any changes and returning the result to STDOUT. SEE ALSO
detox(1), detoxrc(5), detox.tbl(5). HISTORY
detox was originally designed to clean up files that I had received from friends which had been created using other operating systems. It's trivial to create a filename with spaces, parenthesis, brackets, and ampersands under some operating systems. These have special meaning within FreeBSD and Linux, and cause problems when you go to access them. I created inline-detox to clean up these files. AUTHORS
inline-detox was written by Doug Harple. BUGS
Long options don't work under Solaris or Darwin. An error in the config file will cause a segfault as it's going to print the offending word within the config file. BSD
