control-M characters that are NOT end of line characters

[James Hartleroad <jh...@gmail.com>]

For autopopulate I’ve setup for shell scripts to be text/plain, native eol
and executable

  *.ksh    = svn:mime-type=text/plain;svn:eol-style=native;svn:executable



But I have a shell script removeCTLM.ksh that has an embedded cntl-m as
part of a regular expression, for example sed 's/^M//g' $file > tmpfile



I’ve ended up renaming it to removeCTLM.ksk so I could not include the
native eol style

*.ksk   = svn:mime-type=text/x-ksh;svn:executable



But I’m wondering if anyone has a better solution to this so I don’t have
to play games with the filetypes to avoid Subversion from complaining about
the ^M in the file?

No you didn't.  The single quotes protect the \ and it is passed
literally to sed's argv[1].

It's been awhile since I've played with the Korn shell, but this works 
in bash:

#!/bin/bash -f
sed 's/\r//g' $1 > tmpfile

Rather than use a special character, I used the shell's escape sequence.

If this is a shell programming question rather than a subversion
question, then I suggest changing the script to not use an embedded
control-M.  Here are two ways of doing that:

	tr -d '\r' <"$infile" >"$outfile"

	control_M="$(printf '\r')"
	sed -e "s/${control_M}//" <"$infile" >"$outfile"
