Questions tagged [chdir]

chdir (or cd) is a command to change the working directory (change directory). It is part of many operating systems and programming languages. On many OS `chdir()` also is a system call.

cd, sometimes also available as chdir (change directory), is a command line command to change the current working directory in operating systems such as Unix, DOS, OS/2, AmigaOS (where if a bare path is given, cd is implied), Windows, and Linux. It is also available for use in shell scripts and batch files.
