The last cheat sheet I posted was in need of revision and reordering. This one is better than the last--I hope. 



CHEAT SHEET OF SAM
COMMANDS
x cmd - set dot and
run command on each matching line


. -- apply command
to dot


, --  apply command
to whole document





< replace dot
with std input of command


! run the unix
command


> send dot to std
input of command





0<date -- insert
date


>spell -- check
spelling


>wc -l -- count
just the lines


>wc -- do a line,
word and character count





|tr a-z A-Z --
change case


,x/".+"/
y/"/ | tr [:lower:] [:upper:]


OR


,x/".+"/
y/"/ | tr a-z A-Z


-- to capitalise all
letters inside quotes





s/.*/*&*/ --
enclose phrase in asterisks





|fold -s -- break
up/format long lines


|fmt -- idem


|sort -- sort the
file


|uniq -- delete
juxtaposed duplicate lines


|awk '!seen[$0]++'
-- delete non-juxtaposed duplicate lines


,x/\n+/a/\n/ --
finds every occurrence of 1 or more (+) newlines (\n) and appends a
new line.





/vi/ or +/vi/ --
search forward


0/regex/ -- search
from beg. of file forwards


0/regex/+-p --
search for a string and select the whole line that contains it


/vi/+- m 0 selects
and moves the next line containing "vi" to the top of the
file


/vi/+- t 0 selects
and copies the next line with "vi" to the top of the file





$/regex/ -- search
from end of the file backwards





Search for a string,
and then go from search results in sam window to document:


,x g/hello/{


p




}





0,$ t "peter.c"
0 -- copy contents of one to another





, and ; selects
whole document


, equivalent to 0,$


0;5 and 0,5 -
selects 1st five lines





-/^/+#10 -- go to
10th column of current line





B < echo *.org --
One can load multiple files by using <


B < grep -l vi *
will load only those files that contain the string "vi"


D is the complement
of B. It eradicates the file from sam's memory but does not delete
the file from disk! Without a name argument removes current file


e replaces current
file with one specified


f changes the
filename


f <nl? -- set the
current filename to null


n gives a list of
read and loaded files





{} Braces group
commands


[ˆn] any char but n


[nm] n or m





w writes the whole
file, or parts of a file to disk


< cat
/home/red/bin/songs -- insert contents of a file


r
/home/red/bin/songs -- idem


r replaces dot in
the current file with the contents of the file specified





<
/home/red/bin/songs -- insert contents of a script


/home/red/bin/pass google -- output contents of script to sam window





< echo "Hello
world" -- insert ascii code at the current position





x/^/a/  / -- indent
the selected text by 1 tab. x means apply to all lines in the
selection.





sam terminal
information


-----------------------


. indicates the
current file


+ the file has a
window open

p -- prints contents
of dot in sam terminal


= -- prints current
value of dot in sam terminal





,t "junk"
0 -- copy current file to start of file "junk"





Perform conditional
ACTIONS on lines:


g/regexp/ command --
g = if. If dot contains regexp, run command


g/test/d


,x g/vi/p -- if a
line has "vi" print the line in sam window


v/regexp/ command --
If dot does not contain, run a command


,x/.*\n/ g/ed/

change it to "jim" provided it is not "fred....."





,x[a-zA-Z]+/{


g/fred/ v/...../
c/jim/


g/jim/ v/..../
c/fred/


}





In the above command
braces {} allow for multiple commands. The command says: search every
line that contains 1 or more letters, if the line contains "fred"
change it to "jim" and if "jim" change it to
fred, provided "fred" is not "fred." and "jim"
not "jim."





g - "if"


v" - "if
not, unless the regex is"





,| ssam -f
your_script -- apply a sam script
