Either the error comes from somewhere else or it comes from line 3 of the part you have shown. But again: whatever it is supposed to do, i doubt that it does it and i am sure that even if it would do it it should be done differently.

If this is supposed to test if the path /usr/xpg4/bin is alraedy in the PATH it should be:

Code:
  # prepend /usr/xpg4/bin to PATH as needed
  if ! echo "$PATH" | grep -q '\/usr\/xpg4\/bin' ; then
    PATH="/usr/xpg4/bin:${PATH}"

instead of these ridiculous expr-gymnastics.

I hope this helps.

That's not quite correct. Unlike grep, expr searches from the beginning.
The following is correct
Code:
if echo x"${PATH}:" | grep '^x/usr/xpg4/bin:' >/dev/null
then
  :
else
  PATH="/usr/xpg4/bin:${PATH}"

Or
Code:
if expr x"${PATH}:" : x'/usr/xpg4/bin:' >/dev/null
then
  :
else
  PATH="/usr/xpg4/bin:${PATH}"

Also avoids potential problems with Solaris 10 /bin/sh and /bin/grep, and with strange characters in PATH.
But the original is okay. As was already stated, the problem is elsewhere.

NAME
eatmydata - transparently disable fsync() and other data-to-disk synchronization calls SYNOPSIS
eatmydata [--] command [ command arguments ... ] DESCRIPTION
eatmydata runs a command in the environment where data-to-disk synchronization calls (like fsync(), fdatasync(), sync(), msync() and open() O_SYNC / O_DSYNC flags) have no effect. LD_PRELOAD library libeatmydata overrides respective C library calls with custom functions that don't trigger synchronization but return success nevertheless. You may use eatmydata in two ways. In normal mode, just execute eatmydata directly and pass a command-to-be-run and its arguments via com- mand line. In order to use symlink mode, create a symlink to /usr/bin/eatmydata with the filename (a.k.a basename) of another program in the PATH and execute eatmydata via that symlink. Then eatmydata will find that program in the PATH and run it in the libeatmydata environ- ment repassing all command line options. OPTIONS
Please note that eatmydata does not process any command line options in symlink mode. All command line options will be repassed to the underlying executable as-is. command The command to execute. It may be either a full path or the name of the command in PATH. In case command cannot be found in PATH, eatmydata will fail. command arguments Arbitrary number of arguments to pass to the command being executed. -- Optional command separator for compatibility with similar utilities. Ignored at the moment. EXAMPLES
Given PATH is /usr/bin and both /usr/bin/aptitude and /usr/bin/eatmydata are installed, the following: $ ln -s /usr/bin/eatmydata ./aptitude $ ./aptitude moo is equivalent to: $ eatmydata -- aptitude moo Therefore, you may use symlink mode to automatically run specific programs in the libeatmydata environment whenever you run them from PATH. For example, given standard PATH settings, just do: # ln -s /usr/bin/eatmydata /usr/local/bin/aptitude and enjoy sync-free aptitude system-wide. AUTHOR
The eatmydata wrapper around libeatmydata LD_PRELOAD library was written by Modestas Vainius <modax@debian.org> November 2010 eatmydata(1)
