@Franklin52: With the export it is clear for me. It's only a question of getting the $PATH varaible cleaned up. I would do the export afterwards.
But your code

Code:
PATH=`echo "$PATH" | awk -F":" '{for (i=1;i<=NF;i++)if(!x[$i]++)print $i}'`

doesn't work for me, besause I have spaces instead of colons between my directories after execution

Code:
PATH=`printf "$PATH" | /usr/xpg4/bin/awk -v RS=':' -v ORS=":" '!a[$0]++'` | nawk 'NR==1'

Didn't work for me, even, when I put the nawk expressions in the ` `

Sorry I didn't test the command, try this:

Code:
 export PATH=`printf "$PATH" | /usr/xpg4/bin/awk -F":" '{for (i=1;i<=NF;i++)if(!x[$i]++)printf("%s%s", $i,i==NF?"":":")}'

YEAH, that's it. Both solutions work like charm.

@Franklin52: except of the missing ` at the end of your line

Thank you both very much.
