Bash script: Stay Out Of Trouble

String Comparison Result 

string1 = string2                                            True if the strings are equal. 

string1 != string2                                          True if the strings are not equal. 

-n string                                                            True if the string is not null. 

-z string                                                            True if the string is null (an empty string).

Arithmetic Comparison Result 

expression1 -eq expression2 True if the expressions are equal. 

expression1 -ne expression2 True if the expressions are not equal. 

expression1 -gt expression2 True if expression1is greater than expression2. 

expression1 -ge expression2 True if expression1is greater than or equal to 

expression2. 

expression1 -lt expression2 True if expression1is less than expression2. 

expression1 -le expression2 True if expression1is less than or equal to 

expression2. 

! expression True if the expression is false, and vice versa.

File Conditional Result 

-d file True if the file is a directory. 

-e file True if the file exists. Note that, historically, the -e option has not 

been portable, so -f is usually used. 

-f file True if the file is a regular file. 

-g file True if set-group-id is set on file. 

-r file True if the file is readable. 

-s file True if the file has nonzero size. 

-u file True if set-user-id is set on file. 

-w file True if the file is writable. 

-x file True if the file is executable.

Mac OS X Shortcuts

Shortcuts Common to Most Applications

hold option key with menu open	show additional menu options
spacebar	simulate a mouse click on focused object (i.e., the button or control that has a blue halo around it)
command-shift-?	Search application help. As of 10.5, this also FAYT searches available menu items. It also activates the menu bar as keyboard navigable if the search string is empty.
command-shift-+	increase font size
command--	decrease font size
command-,	preferences
command-?	help
command-shift-:	show spelling window
command-;	check spelling
command-A	select all

command-E	use selection for find
command-F	find
command-G	find next
command-shift-G	find previous
command-H	hide application windows
command-option-H	hide windows of other applications
command-J	scroll to selection
command-M	minimize (equivalent to double-clicking the title bar)
command-option-M	minimize all application windows (equivalent to option-double-clicking the title bar or option-clicking the minimize button)
command-N	new
command-O	open

Shortcuts on laptops

On most Mac laptops, some of the function keys (F1 - F12) are used to control hardware features:

F1	decrease brightness
F2	increase brightness
F3	mute on G4s, decrease volume on G3s
F4	decrease volume on G4s, increase volume on G3s
F5	increase volume on G4s, numlock on G3s
F6	Num lock on G4s, mute on G3s
F7	Display mode (mirror or extend external display)
F8	disable backlit keyboards (Aluminum PowerBooks)
F9	decrease keyboard brightness for backlit keyboards
F10	increase keyboard brightness for backlit keyboards
F12	eject (some Macs, namely all MacBooks, MacBook Pros, and newer PowerBooks, place a dedicated eject key next to the F12 key)

Newer Mac laptops (MacBook Pros made after February 2008, MacBooks after November(?) 2007, MacBook Airs), and the Aluminum keyboard, have a different layout for fn keys. Some keys have been added, while the numlock key has been removed and the display mode key has been integrated into the brightness key (see combinations in parenthesis)

F1	decrease brightness (command+F1 changes display mode, option+F1 brings up display prefs)
F2	increase brightness (option+F2 brings up display prefs)
F3	exposé (F3 shows all windows, control+F3 shows app windows, option+F3 brings up exposé prefs, command+F3 shows desktop)
F4	dashboard (option+F4 brings up exposé prefs)
F5	decrease keyboard brightness for backlit keyboards (option+F5 brings up keyboard prefs)
F6	increase keyboard brightness for backlit keyboards (option+F6 brings up keyboard prefs)
F7	media navigation backwards (like hitting back on Apple Remote)
F8	media play/pause (like hitting play/pause on Apple Remote)
F9	media navigation forwards (like hitting next on Apple Remote)
F10	mute volume (option+F10 brings up sound prefs)
F11	decrease volume (option+shift+F11 for incremental decrease, option+F11 brings up sound prefs)
F12	increase volume (option+shift+F12 for incremental increase, option+F12 brings up sound prefs)
