Hamilton C shell Substitution Modifiers

Substitution Modifiers

Substitution modifiers can be applied to any command, variable or history substitution. Also, any number in a row can be applied, as desired.

	Operator	Meaning
	`:`n	nth word
	`:#`	Count the number of words
	`:^`	Word number 1, counting from 0
	`:$`	Last word
	`:%`	Word matched by a `!?`str`?`history search
	`:`n`-`m	nth through mth words
	`:-`n	0 through nth words
	`:`n`-`	nth through next-to-last words
	`:`n`*`	nth through last word
	`:*`	1 through last word
	`:q`	Single-quote each word
	`:s/`str1`/`str2`/`	Substitute str2 for str1 and then reparse into words. Match failures are considered to be errors unless ignoreerrors == 2.
	`:S/`str1`/`str2`/`	Substitute str2 for str1 but leave it as a single string. Also, failure to match is not considered an error.
	`:&`	Repeat last substitution
	`:g`	Global editing: as a prefix character to any of the other editing operators, it means apply the edit operation everywhere it matches, not just the first occurrence.
	`:x`	Treat each word as a string, break it up into words, then single-quote each word.
	`:p`	Print the substitution but don't execute the statement. (Ignored except in history substitutions.)
