You may use this function. If the file name is given without relative path, then it is assumed to be present in the current working directory:

abspath() { old=`pwd`;new=$(dirname "$1");if [ "$new" != "." ]; then cd $new; fi;file=`pwd`/$(basename "$1");cd $old;echo $file; }

Usage:

$ abspath file.txt
/I/am/in/present/dir/file.txt

Usage with relative path:

$ abspath ../../some/dir/some-file.txt
/I/am/in/some/dir/some-file.txt

With spaces in file name:

$ abspath "../../some/dir/another file.txt"
/I/am/in/some/dir/another file.txt
