This version uses Pipes, but is easier for the common user to grasp... instead of using sed or some other more complicated method, it uses the tr command

( IFS=:; for p in $PATH; do echo $p; done )

The output of "echo $PATH" is hard to read, this is much easier. The parentheses ensure that the change to the input field separator (IFS) only happens the the sub shell and not affecting the current shell.

echo -e ${PATH//:/\\n}
echo src::${PATH} | awk 'BEGIN{pwd=ENVIRON["PWD"];RS=":";FS="\n"}!$1{$1=pwd}$1!~/^\//{$1=pwd"/"$1}{print $1}'

Removes trailing newline; colon becomes record separator and newline becomes field separator, only the first field is ever printed. Replaces empty entries with $PWD. Also prepend relative directories (like ".") with the current directory ($PWD). Can change PWD with env(1) to get tricky in (non-Bourne) scripts.

print -l $path

This doesn't work in bash, but in zsh you can typeset -T to bind a scalar variable to an array. $PATH and $path behave this way by default.

Know a better way?

If you can do better, submit your command here.

What others think

Shouldn't it be?: echo "${PATH//:/$'\n'}"

Comment by plasticdoc 243 weeks ago

Yes, it's like plasticdoc said, if not they will be displayed in one line, space separated.

Comment by inkel 243 weeks ago
echo -e "${PATH//:/\n}"

Ya plasticdoc is correct. Using that builtin version is by far the best.
