Re^2: Printing columns to a single file
in thread Printing columns to a single file
Note that you did not follow any of the advice I listed above. You did not show a sample of input. You did not show a sample of output. You did not explain why you are using a one-liner. You did not say why the provided code modification didn't do what you needed. Why are you making it hard for me to help you?
I have files like file 1,file 2,file 2 etc like in hundreds...
You can use opendir
to cycle over, as I said previously, or use glob
if you are so inclined. -n
to read files (see I/O Operators
), so it will implicitly cycle over the argument list - thus *.gcount
will be expanded by the shell into a full file list and get cycled over.
It has data in columns so I would like to extract 0 and 4 column from every file
So why aren't you using Text::CSV
to read it?
i am asking that if theres any posibility to include every thing in single code
A great deal is possible. That doesn't make it a good idea. After all this time and effort, a simple script would have been written and done already. That certainly could be considered a "single code". Why are you hung up on one-liners?
