My which script

[G4143]

This is my simple which script...which behaves like the command 'which'

Code: Select all

#! /bin/sh

echo -n "enter file to find->"
read myfile

fslash="/"

IFS=":"

set $PATH

for p in $*
do
   if ls "$p${fslash}${myfile}" > /dev/null 2>&1
   then
      echo -n "The file '$myfile' exists in-> "
      echo $p${fslash}${myfile}
      exit 0
   fi
done

echo "'$myfile' does not exist"

exit 1

Thanks for the pointers. I reduced my script to this..

Code: Select all

#! /bin/sh

echo -n "enter filename->"
read mycomm

IFS=":"

for i in $PATH
do
   if [ -f "${i}/$mycomm" ]
   then
      echo ${i}/$mycomm
      exit 0
   fi
done

   echo "'$mycomm' not found!"

exit 1
