Bad : modifier in $ (.)

Question

I want to set environment variable in linux and did the same by giving command

 export PATH=$PATH:.

But getting error Bad : modifier in $ (.).

Can some one help this. I tried with bash shell and ksh

Answer 1

Dont forget to escape the colon

setenv PYTHONPATH $PYTHONPATH\:/disk1/mypath

Answer 2

You might want to try this:

export PATH="${PATH}:."

I don't like having the current directory in the path, but at the end it's fairly safe.

Answer 3

Bad : modifier in $ (.).

This is not a Bash error, nor is it from Ksh: it's from C-shell or one of its clones such as Tcsh.

You want:

setenv PATH ${PATH}:.

But you should not put . in your ${PATH}, it's a well-known security risk.
