Interesting, but unfortunally, a bit slow. grep rocks when it comes to speed:
#!/bin/sh FILE=/home/abigail/Words/enable.lst PATTERNS=" abc sch[ae] .*a.*e.*i.*o.*u.* ^[[:xdigit:]]+$ (a|b)(c|d)(e|f) " PROGRAMS=("/bin/grep -E" ./grepp) OUTPUT=(/tmp/grep.out /tmp/grepp.out) i=0 while [ $i -lt ${#PROGRAMS[*]} ] do echo -n ${PROGRAMS[$i]} time for pat in $PATTERNS do ${PROGRAMS[$i]} $pat $FILE done > ${OUTPUT[$i]} i=$((i + 1)) done i=1 while [ $i -lt ${#OUTPUT[*]} ] do diff ${OUTPUT[0]} ${OUTPUT[$i]} i=$((i + 1)) done rm -f ${OUTPUT[*]} /bin/grep -E real 0m0.070s user 0m0.060s sys 0m0.010s ./grepp real 0m2.774s user 0m2.610s sys 0m0.030s
