merging sed commands
Hi,

I've a shell that uses two sed commands to tailor a file.

sed 's/ */ /g' | sed 's/%/%%/g'

Is it possible to merge this in to a single sed?

Thanks!

shtool-install

SHTOOL-INSTALL.TMP(1)					      GNU Portable Shell Tool					     SHTOOL-INSTALL.TMP(1)

NAME

       shtool-install - GNU shtool install(1) command

SYNOPSIS

       shtool install [-v|--verbose] [-t|--trace] [-d|--mkdir] [-c|--copy] [-C|--compare-copy] [-s|--strip] [-m|--mode mode] [-o|--owner owner]
       [-g|--group group] [-e|--exec sed-cmd] file [file ...]  path

DESCRIPTION

       This command installs a one or more files to a given target path providing all important options of the BSD install(1) command.	The trick
       is that the functionality is provided in a portable way.

OPTIONS

       The following command line options are available.

       -v, --verbose
	   Display some processing information.

       -t, --trace
	   Enable the output of the essential shell commands which are executed.

       -d, --mkdir
	   To maximize BSD compatiblity, the BSD "shtool "install -d"" usage is internally mapped to the "shtool "mkdir -f -p -m 755"" command.

       -c, --copy
	   Copy the file to the target path. Default is to move.

       -C, --compare-copy
	   Same as -c except if the destination file already exists and is identical to the source file, no installation is done and the target
	   remains untouched.

       -s, --strip
	   This option strips program executables during the installation, see strip(1). Default is to install verbatim.

       -m, --mode mode
	   The file mode applied to the target, see chmod(1). Setting mode to ""-"" skips this step and leaves the operating system default which
	   is usually based on umask(1). Some file modes require superuser privileges to be set. Default is 0755.

       -o, --owner owner
	   The file owner name or id applied to the target, see chown(1). This option requires superuser privileges to execute. Default is to skip
	   this step and leave the operating system default which is usually based on the executing uid or the parent setuid directory.

       -g, --group group
	   The file group name or id applied to the target, see chgrp(1). This option requires superuser privileges to execute to the fullest
	   extend, otherwise the choice of group is limited on most operating systems.	Default is to skip this step and leave the operating
	   system default which is usually based on the executing gid or the parent setgid directory.

       -e, --exec sed-cmd
	   This option can be used one or multiple times to apply one or more sed(1) commands to the file contents during installation.

EXAMPLE

	#   Makefile
	install:
	     :
	    shtool install -c -s -m 4755 foo $(bindir)/
	    shtool install -c -m 644 foo.man $(mandir)/man1/foo.1
	    shtool install -c -m 644 -e "s/@p@/$prefix/g" foo.conf $(etcdir)/

HISTORY

       The GNU shtool install command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1997 for GNU shtool. It was prompted
       by portability issues in the installation procedures of OSSP libraries.

SEE ALSO

       shtool(1), umask(1), chmod(1), chown(1), chgrp(1), strip(1), sed(1).
