The loop
Quote:
for i in *.tmp; do cp "$i" "${i%.tmp}"_New.tmp; done
is nonsense, because the outer loop cycles through the .tmp files already.
Code:
for i in *.tmp
do
    if grep 'find[[:blank:]].*[[:blank:]]with[[:blank:]]' "$i" >/dev/null
    then
      # file backup
      cp "$i" "$i".bak
   
      sed -e 's/find\([[:blank:]].*\)[[:blank:]]with[[:blank:]][[:blank:]]*/where\1:/' \
          -e 's/^[[:blank:]]*;[[:blank:]]*$//' "$i".bak > "$i"

    fi
done

Variables like $i should be quoted when used as command arguments.
You can also delete ";" and "run" with the sed command. The latter is left as an exercise (this smells like homework).

ATF-SH(1)						    BSD General Commands Manual 						 ATF-SH(1)

NAME
atf-sh [-s shell] -- interpreter for shell-based test programs SYNOPSIS
atf-sh script DESCRIPTION
atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library. atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL. atf-sh executes the inter- preter, loads the atf-sh(3) library and then runs the script. You must consider atf-sh to be a POSIX shell by default and thus should not use any non-standard extensions. The following options are available: -s shell Specifies the shell to use instead of the value provided by ATF_SHELL. ENVIRONMENT
ATF_LIBEXECDIR Overrides the builtin directory where atf-sh is located. Should not be overridden other than for testing purposes. ATF_PKGDATADIR Overrides the builtin directory where libatf-sh.subr is located. Should not be overridden other than for testing purposes. ATF_SHELL Path to the system shell to be used in the generated scripts. Scripts must not rely on this variable being set to select a specific interpreter. EXAMPLES
Scripts using atf-sh(3) should start with: #! /usr/bin/env atf-sh Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh. Instead, you have to hardcode the path to atf-sh in the script and then use the -s option afterwards as a single parameter: #! /path/to/bin/atf-sh -s/bin/bash ENVIRONMENT
ATF_SHELL Path to the system shell to be used in the generated scripts. SEE ALSO
