What Others Think

Don't sort the path because there may be two programs with the same name and the first in the path should show up first. Also, take advantage of grep regular expression and remove the sed scripts. Handle empty string cases. function sepath { echo ${PATH} | tr : \\n | while read L; do find ${L:-"."} -type d ! -path ${L:-"."} -prune -o \( -type f -o -type l \) 2>/dev/null | grep -i "${L:-"."}/.*${*}"; done; }

thanks for your comment arcege but your modifications are not efficients. for example: sepath ^ps will not work with your hack. however, you right, i should not sort the PATH. Mobidyc
