need to read 3° character from a text file
Hi,

I need a script to read the n° character from a text file.
eg: if the text file contains the line "123456" ,I nedd a command to display the number 4, as an example.

I tried with awk and printf but it seems only works with words separated with spaces, but in this case I have only one word "123456" and the characters are not separated.


Thanks in advance for your kindly help.
