Tilde notation

A ~ (tilde) can be used from the z/OS® shell in several forms:

Notation	Meaning
~	Your home directory (that is, the directory given by your HOME environment variable). The command: `cp ~/file1 file2` copies file1 in your home directory into file2 in your working directory. This works regardless of what your working directory is. `cp file1 ~/dir` copies file1 from the working directory into dir in your home directory.
~ +	The variable $PWD (which contains the name of your working directory).
~ –	The variable $OLDPWD (which gives the name of the working directory you were in immediately before the last cd command).
~login name	That user's home directory. Example: To display the profile file of allane, from that user's home directory, issue: `cat ~allane/.profile` This is useful if there are a group of you working on a project and you have read-write access to some of each other's files. Note: In the z/OS shell, your login name is your TSO/E user ID.
