Avoiding external tools viz. basename, cut, awk and minimising the use of pipes
Even this uses ls and head and makes the wild assumption that the latest version of any Provider's files will be the one with the most recent timestamp. It also assumes that there will be at least one existing file for each provider. The following script is much more complex than balajesuri's script but will create version 1 of a file for a provider that doesn't currently have any files, will use the highest numbered version rather than the last touched version of a Provider's files if more than one exists, and will print a diagnostic and exit if no provider code is specified or if an unknown provider code is specified:
Note that although this script uses $!/bin/bash, this code will work with any POSIX conforming shell (including, but not limited to, bash and ksh) as long as nothing bash specific appears in the sourced script.

Hello,
Here's a file of mine:
key1:431
key2:159
key3:998

The output would be:

Two questions:
1) Is there a way to create a new column (i.e. ID) to an existing file containing data and the new column ID populate as an auto incrementing number?
for example:
(Current file has headers and is PIPE delimited.)
**data looks like this**
"COL1"|"COL2"|"COL3"|"COL4"|"COL5"... (0 Replies)

I am using cygwin on Windows 7.
I am starting with a data file with filename "name_1.ext", like "20180831_snapgenotypes_1.csv".
The "_1" before ".ext" is a version number. Integers (0-99) are sufficient. They don't have to be like "1.0.0".
The filename may... (2 Replies)
