The

Answer 1

In mac mentioned below line works. No need to add any fancy lines.

> pwd filename

Answer 2

Beside "readlink -f" , another commonly used command:

$find  /the/long/path/but/I/can/use/TAB/to/auto/it/to/ -name myfile
/the/long/path/but/I/can/use/TAB/to/auto/it/to/myfile
$

This also give the full path and file name at console

Off-topic: This method just gives relative links, not absolute. The readlink -f command is the right one.

Answer 3

Use readlink:

readlink -f file.txt

Answer 4

This works with both Linux and Mac OSX ..

 echo $(pwd)$/$(ls file.txt)

Answer 5

The following usually does the trick:

 echo "$(cd "$(dirname "$1")" && pwd -P)/$(basename "$1")"

Answer 6

This worked pretty well for me. It doesn't rely on the file system (a pro/con depending on need) so it'll be fast; and, it should be portable to most any *NIX. It does assume the passed string is indeed relative to the PWD and not some other directory.

function abspath () {
   echo $1 | awk '\
      # Root parent directory refs to the PWD for replacement below
      /^\.\.\// { sub("^", "./") } \
      # Replace the symbolic PWD refs with the absolute PWD \
      /^\.\//   { sub("^\.", ENVIRON["PWD"])} \
      # Print absolute paths \
      /^\//   {print} \'
}
