Mastering The Linux Shell - Bash Shortcuts Explained (Now With Cheat Sheets)
During my day-to-day activities, I use the Bash shell a lot. My #1 policy is to optimize the most frequently used activities as much as possible, so Ive compiled these handy bash shortcuts and hints (tested in SecureCRT on Windows and Konsole on Linux). The article only touches on the default bash mode emacs, not vi. If you havent specifically assigned your shell mode to vi (set o vi), youre almost certainly using the emacs mode. Learn these and your shell productivity will skyrocket, I guarantee it.
Update #1: By the way, as duly noted in the comments, all of these tricks work on the mysql command line, so you can, for example, ctrl-R through your previously executed mysql commands.
Update #2: In response to a few people saying this list is too short and [he] could've added something to it, to atleast make it look longer (quote from one of Stumbleupon reviewers), I want to clarify something. I deliberately did not include every single bash shortcut there is. I included what I personally thought were the best and most useful commands. I did not want to make the list too cluttered and wanted the cheat sheet to fit on one page without going to a smaller font size.
Update #3: For all the WP-Greetbox haters out there (apparently there are a few), please dont mix hating content with hating the greeting. A few stumblers seem to be annoyed at the plugin (written by my good friend Thaya btw) but I frankly dont see how this justifies such negativity. /vent
Without further ado (see bottom of the page for cheat sheet download links):
|
Keyboard shortcut |
Action |
|
Navigation |
|
| ctrl-A | Go to the beginning of the line (note that if you use GNU screen, you can use the Home button to do this, especially considering that ctrl-A is a special control character in screen). |
| ctrl-E | Go to the end of the line (note that if you use GNU screen, you can use the End button to do this). |
| alt-B or esc, left arrow | Jump back one word*. |
| alt-F or esc, right arrow | Jump forward one word*. |
| Ctrl-PgUp or Shift-PgUp | This may or may not work, and it works differently on different console apps. It will either scroll up one line at a time, 1 page at a time, or it may not work at all. I'm inclined to think it's not a bash shortcut at all. |
| Ctrl-PgDn or Shift-PgDn | Same as the above but scrolling is done in the opposite direction. |
| Up/Down | Previous/Next command in history. This one is way too obvious but I'm including it for completeness. |
|
Command Line Manipulation |
|
| ctrl-W | Cut to the previous white space (one word*). |
| alt-backspace | Cut to the previous non-alphanumeric character (different from ctrl-W, for example, abc;bcd will cut to abc;). |
| ctrl-K | Cut everything to the end of the line. |
| ctrl-U | Cut everything to the beginning of the line. |
| ctrl-T | Flip the current character with the previous one. I almost never use this. Never mind, I never use it, but someone might find it useful. |
| ctrl-Y | Paste whatever was cut by the last cut command. |
| ctrl-V | Insert the next character literally. For example, Ctrl-V TAB inserts the actual TAB character. This shortcut is often misunderstood because of mistyping ctrl-V and not realizing what it does. |
|
Terminal control |
|
| ctrl-L | Clear screen while keeping whatever is already typed in the command line intact. |
| ctrl-S | Suspend currently running terminal. |
| ctrl-Q | Unsuspend the terminal suspended by ctrl-S. You need to be aware of this shortcut because 99% of the time youve accidentally pressed ctrl-S and need to undo its effects. |
| ctrl-R | History search. For example, ctrl-R svn ctrl-R ctrl-R will cycle through all recently run commands with the svn in them. It is one of the most useful shortcuts in bash. |
| ctrl-Z | Suspend the currently running process (usually followed by bg to resume it in the background or fg to resume in the foreground). |
| TAB | Autocomplete. Start typing, then hit TAB. You will either get a list of possible completion values (2 TABs needed) or the only choice will be filled in (only 1 TAB is needed). This shortcut is quite obvious and well known, so I put it at the bottom of the list. |
* Note that a word seems to be defined as a series of alphanumeric characters, so deleting one word would delete to the next non-alphanumeric character.
Hope you guys will find this list helpful. I think it is relatively complete, but feel free to add any omissions. Im also considering making it into a PDF cheat sheet. Here are the cheat sheets I made:
