Termux Guide Update
softbrick phone ko guys kaya gawa muna ako ng magulong tut para sa inyo. Practice ko nadin tong BBCode. start na agad..
Termux CMDLine Basic
Basic Bash Scripting and Command Chaining
Command Chaining
for those to lazy to type each command consecutively you can just chain them and be done with it.
just add a semicolon(after each command and type the next one, this simple chain can last for as long as you can type.
Bash:echo "Sore-Scythe"; echo "is"; echo "so" && echo "effing"; echo 'handsome'
but what if we want the first command to pass it's output to the second one?
we do it with a pipe(|)
Bash:echo "Sore-Scythe is so effing ugly"|sed 's\ugly\handsome\' # you can use pipe with a lot of commands but not all of them so experiment or search. # you can also pipe the cat commmand which is an abbreviation for "read that file" cat .bashrc|sed -E 's/[a-zA-Z]+/PANGET/'
for those that want the chain to stop if a command fails and those that need a command to run only when the previous command fails.
Bash:# to stop the chain if the cat command fails use && cat secret_born_bookmarks.txt && echo "sadly there is none" # to run a command when the previous one fails use double ***** (||) cat secret_born_bookmarks.txt || echo "sadly there is no such file" # that's about it I think
now for those that need the output of a command to be treated as an argument, use a subshell.
a subshell is spawned when you put commands inside a "$()"
Bash:# for example echo "sdcard files $(echo 'ZGVsZXRlZAo='|base64 -d)"s # the shell stops when it encounter a $() # it runs it then swap the $() with its output # then continues echo "I am in the main shell" "$(echo "I'm in the subshell")"
Basic scripting
i'll mostly talk about loops here.
For loop
Bash:# this is used to loop over a list or an array. that means it will run command/s on each item in the list/array # keep in mind that the list can come from anywhere be that an output of ls # or the lines in a file # dumb looping - useful when you forgot the technique to use for count in 1 2 3 4 5 do echo "first command, " $(expr $count + $count) echo "second command, $(expr $count * $count)" done # loop from n to n for count in {1..200} do echo "number is $count with $(expr 200 - $count) left to go" done # the first line defines count as the name for our main variable # its value changes for each iteration. this loop continues for each # item in the list which is "1 2 3 4 5" in the first example # and numbers 1 to 200 in the second. # for loop is to avoid repeatedly running commands like number=1;echo "first command, $(expr $number + $number)";echo "second command, $(expr $number \* $number)" number=2;echo "first command, $(expr $number + $number)";echo "second command, $(expr $number \* $number)" number=3;echo "first command, $(expr $number + $number)";echo "second command, $(expr $number \* $number)" number=4;echo "first command, $(expr $number + $number)";echo "second command, $(expr $number \* $number)" number=5;echo "first command, $(expr $number + $number)";echo "second command, $(expr $number \* $number)"
will continue writing later...
comment down what you think i should write about and i'll try to do so....
