Question about searching a number in file suffix

2 views (last 30 days)
I have a question about a command I would like to use. I have several files with multiple suffixes, for example file_1.txt, file_2.txt, file_3.txt etc.
I would like to read a specific file depending on a value of a variable. For example if my value is equal to 4 I would like to read file file_4.txt. if my value is equal to 5 I would like to read file file_5.txt.
Which command should I use in order to make it?
Coule you please help me?
