I’m not sure if this is possible, but I’m wondering if it’d be able to split a file into multiple files – dependent on the amount of a specified character there is on each line.
Lets use a colon (:) as an example
File.txt contains the following data (example):
Stack:Overflow
Stack:Overflow:Flow
Stack:Over:Flow:Com
Entire line containing 1 colon, goes to 1.txt
Entire line containing 2 colons, goes to 2.txt
Entire line containing 3 colons, goes to 3.txt
(And of course) there wouldn’t be a limit to the amount of colons, and format may not necessarily always match the exampled pattern.
Sorry if this is a vague question, I’m first time posting on StackOverflow in a long.
Another side question:
Inserting a specific character between 2 different regexs.
Data:
Stack@Stack.Stack192.168.0.1
I’m trying to insert a delimiter which will be ":"
Between 2 different regexes.
Regex #1 being: [A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,6}
Regex #2 being: [0-9]{1,4}\.[0-9]{1,4}\.[0-9]{1,4}\.[0-9]{1,4}
So the desired output would be:
Stack@Stack.Stack:192.168.0.1
>Solution :
With GNU AWK this approach will provide your expected outcome:
awk -F":" '{print > ((NF - 1)".txt")}' file.txt
NB. if you have a large number of delimiters (hundreds – thousands) you may also run into trouble for having too many open files (I believe ulimit -n will tell you how many different files you can have open at one time; on my system it’s 256)
