8. UNIX for Dummies Questions & Answers
Hi,
I couldn't figure how to extract until last occurence of a character.
I have the string ./dir1/file1/abc.sh
The output should be /dir1/file1
So, the command should display the path until last occurence of "/".
Thanks. (3 Replies)

REALPATH(3) 1 REALPATH(3)
realpath - Returns canonicalized absolute pathname
SYNOPSIS
string realpath (string $path)
DESCRIPTION
realpath(3) expands all symbolic links and resolves references to '/./', '/../' and extra '/' characters in the input $path and returns the
canonicalized absolute pathname.
PARAMETERS
o $path
- The path being checked.
Note
Whilst a path must be supplied, the value can be blank or NULL In these cases, the value is interpreted as the current
directory.
RETURN VALUES
Returns the canonicalized absolute pathname on success. The resulting path will have no symbolic link, '/./' or '/../' components.
realpath(3) returns FALSE on failure, e.g. if the file does not exist.
Note
The running script must have executable permissions on all directories in the hierarchy, otherwise realpath(3) will return FALSE.
Note
Because PHP's integer type is signed and many platforms use 32bit integers, some filesystem functions may return unexpected results
for files which are larger than 2GB.
