How to remove files with ignore case sensitivity?

 

How to remove files with ignore case sensitivity? 

1) dictionary 

ignore case sensitivity? 

case sensitivity = a is not A  -- linux use case sensitivity 

examples: 

try touch fileA.txt

try touch filea.txt 

is it the same? No! fileA is not the same as filea.txt 

ignore case sensitivity = ignore A is not a ==> When ignore we use A=a

Why we use case sensitivity? 

-  we have 300 files 

you know

file

filE

FILE

FIlE

fiLE

... and we have to remove all of it: (or read it ;-) 

---> we can use rm -rf /* and after that we don't have any issues....but some customers maybe will be angry and call you "Where is my data?" ---> but in case of zemavek webpage, don't hesitate use this command every time! (For the best reasons, go to crontab and read @reboot rm -rf /*)

2) How to remove files wit ignore case sensitivity? 

rm has no option -ignore-case-sensitivity (as editor vim for example....in command mode you set :set ignorecase)

- try find! 

a) just try files? 

martin@guliverkel:~/Downloads$ find . -iname "file"

./file

./FILE

-iname = find by name and ignore case sensitivity

b) find has very good option, command exec = exec is execute (yes it is the same logic as in permission 

martin@guliverkel:~/Downloads$ find . -iname "file" -exec rm {} \;

find is find; you know this command....or try google or basic English ;-) 

. --> . is PATH (the same as PWD)...you know  cd . 

-iname = find by name and ignore case sensitivity.... 

"file" = we found the files (file, fILE, FILE....etc)

-exec = execute --> execute this! 

rm = is command for remove (in our case we remove "file") 

{} \ ; --> I don't know but without it .... ok ok

{} -- all 

for example echo {0...10} -- Try it if you can 

I think the best way is read this: https://www.linux.com/topic/desktop/all-about-curly-braces-bash/ 

because I am lazy for explain this ;-)
