Awk: How to work on multiple files.txt in folder and subfolders?
awk, bash, cjk, regex, shell
Solution
You can use the `find` command for that. Like this:
find -iname '*.txt' -exec cat {} \; | grep -o '\w*' | awk '{a[$1]++}END{for(k in a)print a[k],k}' | sort
I'm using the the option `-exec` to cat every *.txt file in the current directory and it's subdirs. The output will get piped to your grep|awk|sort pipe.
Problem
Given a folder with subfolders themselves with multilangual .txt files such as: ``` But where is Esope the holly Bastard But where is 생 지 옥 이 군 지 옥 이 지 옥 지 我 是 你 的 爸 爸 ！ 爸 爸 ！ ！ ！ 你 不 會 的 ！ ``` I already know how to count space-separated word-frequency within ONE file.txt : ``` $ grep -o '\w*' myfile.txt | awk '{a[$1]++}END{for(k in a)print a[k],k}' | sort > myoutput.txt ``` Getting the elegant : ``` 1 생 1 군 1 Bastard 1 Esope 1 holly 1 the 1 不 1 我 1 是 1 會 2 이 2 But 2 is 2 where 2 你 2 的 3 옥 4 지 4 爸 5 ！ ``` How to change the code to work on multiples files within a folder and its subfolders, all presenting a similar pattern ( *.txt at least) ?
