Package: php5-common Version: 5.4.35-0+deb7u1 Running the sessionclean script shiped with php5-common results in help for sed, since sed do not support -z options.
Additional information for php-common: Depends: sed (>= 4.1.1-1), psmisc (>= 22.15-1~), lsof, libc6 (>= 2.4), ucf Output: $ /usr/lib/php5/sessionclean sed: invalid option -- 'z' Usage: sed [OPTION]... {script-only-if-no-other-script} [input-file]... -n, --quiet, --silent suppress automatic printing of pattern space -e script, --expression=script add the script to the commands to be executed -f script-file, --file=script-file add the contents of script-file to the commands to be executed --follow-symlinks follow symlinks when processing in place -i[SUFFIX], --in-place[=SUFFIX] edit files in place (makes backup if extension supplied) -l N, --line-length=N specify the desired line-wrap length for the `l' command --posix disable all GNU extensions. -r, --regexp-extended use extended regular expressions in the script. -s, --separate consider files as separate rather than as a single continuous long stream. -u, --unbuffered load minimal amounts of data from the input files and flush the output buffers more often --help display this help and exit --version output version information and exit If no -e, --expression, -f, or --file option is given, then the first non-option argument is taken as the sed script to interpret. All remaining arguments are names of input files; if no input files are specified, then the standard input is read. GNU sed home page: <http://www.gnu.org/software/sed/>.
