What is a regular expression: A very flexible way of defining patterns in text. By writing Special characters, you can specify what to search: . matches any character \\d matches any digit \\w matches any letter (ascii) \\s matches any whitespace | either the preceding or next expression may match {m,n} at least m and at most n repetitions of the preceding * zero or more repetitions of the preceding + one or more repetitions of the preceding ? at most one repetition of the preceding ^ or $ the beginning or the end of the string More at: http://www.ruby-doc.org/docs/UsersGuide/rg/regexp.html If you're just searching or a simple string, it's usually enough to write it down. To escape the special characters, precede them with a \\ key:l Space: Mark a file. v: Reverse markings V: Clear markings l or RIGHT Enter the directory or run the file in mode 0, flag "a" L Run in a different way: mode 1, no flags rr Run with mode and flags . example: r3adr Default mode: 0, default flags: no flags at all What are flags: Letters that specify details on how ranger should run the program. Capital letters reverse the function. use as many flags as you want. a Run the selection rather than just the highlighted file t Run in a detached terminal (implies d) d or e Run as a detached process inside the current terminal w Wait for a after execution of the programm What are modes: A number from 0 to infinity that specifies what shell command should be executed, since most file types have different ways to be run. You can set up the commands for each type in the file ranger/data/apps.rb key:c the word "selection" means if you marked something: all marked items and NOT the highlighted item otherwise: the selected item. mkdir creates directory touch creates file yy or cp Memorize selection cut like cp, but move instead of copy if "p" is pressed p Copy memorized files here. o Copy selection to the bookmarked dir (see ?g) use deleteing commands with caution! dd: Move selection to ~/.trash and memorize it's new path (so it can be pasted with p) dfd: Deletes the selection or empty directory delete: Remove whole selection with all contents mv: move/rename file to cw: same as mv A: write "cw " to the key buffer key:o t Toggle Option S Change Sorting E Edit file s Enter Shell !

To use this feature, do the following: 1. enter this line into your ~/.bashrc (if you use bash. other shells should be similar): alias ranger='cd "`/path/to/ranger --cd 3>&1 1>&2`"' 2. reload your bashrc by typing: source ~/.bashrc 3. type in ranger, navigate and quit. in bash, you should still be in the directory where you left with ranger. The --cd switch writes the pwd to the 3rd file descriptor on exit, the cd command will read from it and change the dir accordingly. If you decide that you don't want to change the directory after all, you can toggle the --cd switch inside ranger by typing tc. Also, typing ZX quits ranger with the --cd switch inverted.
