22 # Instructions: |
|
23 # 'dm' will manage a list of id-directory. 'dmcd' will allow the current shell to |
|
24 # change to the directory given by 'id'. |
|
25 # |
|
26 # Examples: |
|
27 # $ dm 1 /tmp # Adds the id '1' for /tmp |
|
28 # $ dm 2 . # Adds the id '2' for the current dir |
|
29 # $ dmcd 1 # Goes to /tmp |
|
30 # $ dmcd 2 # Goes to what was your current dir |
|
31 # $ dm -d 2 # Deletes the entry for '2'. |
|
32 # $ dm # Shows your 'database' |
|
33 # 1 /tmp |
|
34 # $ dm -h # Shows help, and defines 'dmcd' for sh. |
|
35 # |
|
36 # In order to use 'dmcd', you should define the function |
|
37 # given by "dm -h" in your shell. Put it in your bashrc or |
|
38 # a file like that. |
|
39 # |
|
40 # Your directory database is stored in ~/.dm . |
