Referencing previous commands
$? |
exit status of last command |
$0 |
$# |
# args passed to current script/ function |
$* |
list of args passed, as a space-separated string |
$@ |
list of args passed, as a delimited list |
$_ |
most recent arg |
$! |
PID of last bg command |
$$ |
pid of current shell |
$- |
option flags used |
$n |
reference to arg n in last command |
Bash History: "Event Designators"
!n |
Repeat nth command |
!-n |
Repeat command n lines back |
!! |
Last command; synonymous w/ !-1 |
!string |
Most recent command starting with string |
!?string? |
Most recent command containing string |
^str1^str2^ |
repeat last command, replacing str1 w/ str2 |
!!:s/str1/str2 |
synonymous with the above |
!$ |
last arg of last cmd; synonymous w/ !!:$ |
History "Word Designators"
$ |
last argument |
0 (zero) |
0th argument, usually the cmd word |
n |
the nth word (n-1 arg) |
^ |
1st argument (word 1) |
% |
word matched by most recent ?str? search |
* |
all words except the 0th (i.e., all args) |
Word designator is separated from event by a colon ':' unless it is ^,$,*,-,%.
For example, !!:$ becomes !$.
Words are counted from 0, so the command itself is 0.
Words can be used with events. For example, !foo:3 finds the last command starting with foo, then takes the 3rd word (2nd argument).
History: Modifiers
[g]s/str1/str2 |
& |
repeat prev substitution |
p |
prints resulting command but doesn't execute it |
e |
removes all but trailing suffix (e.g., .txt) |
r |
removes trailing suffix, keeps basename |
h |
removes "trailing" last dir in pathname, keeping "head" (path to that directory's directory) |
t |
removes all dirs in path except the last one ("tail") |
Used after the event and word designators.
Gets very complex.
I'm only showing the sed-like ones here.
