LinuxQuestions.org - set path problem solved

Hi!

Actually this is not a question but rather an answer to my own questions/problems, which I think is worth posting here (thanx to acid_kewpie and Dark_Helmet for suggestions on this topic posted previously).
So here it goes:

this is a (bash) function for checking your path entries for duplicates and that evil dot (.) :)

Code:

function setpath() {

  newpath=""



  for old in $(echo $1 | sed -e "s/:/\n/g" | grep -v "\.")

  do

    if [ -d "$old" ]

    then

      bad=0

      for new in $(echo $newpath | sed -e "s/:/\n/g")

      do

        if [ "$old" == "$new" ]

        then

          bad=1

        fi

      done

      if [ "$bad" == "0" ]

      then

        if [ "$newpath" == "" ]

        then

          newpath=$old

        else

          newpath=${newpath}:$old

        fi

      fi

    fi

  done

 }

... it takes only 1 argument which is a path to test.
To test your $MANPATH you should put:

Code:

setpath "$MANPATH"

export MANPATH=$newpath

after the function ... setting the path to check before it is required :)

Hope this helps anyone - it sure has served me good.

Enjoy,

Luka
