A shell script is slower than sed and awk and even perl if the input file is big enough.
(BTW in my measurements bash was much slower than ksh.)

so that it will not only take out abc from the filename but also take out any numbers that might be in the filename as well.
An example would be,

The bash below executes and does find all the .bam files in each R_2019 folder. However set -x shows that the .bam extension only gets removed from one .bam file in each folder (appears to be the last in each). Why is it not removing the extension from each (this is $SAMPLE)? Thank you :).

update-metainit
UPDATE-METAINIT(1) User Contributed Perl Documentation UPDATE-METAINIT(1)NAME
update-metainit - Generates init scripts
SYNOPSIS
update-metainit [--remove initname [--purge] ]
DESCRIPTION
Metainit solves the problem of writing good init scripts. Instead of manually creating these important files, they are derived from a
declaritive description in the metainit files in /etc/metainit. These files can be shipped with packages or created by the local adminis-
trator.
If update-metainit called without argument, it will regenerate init scripts for all the files in /etc/metainit. The generated files contain
a large warning in form of a comment that they will be overridden. Modifications are preferably done in the files in /etc/metainit and made
effective by running update-metainit. If needed, the administrator can prevent modified init files by removing the warning comment.
OPTIONS --remove initname
This command will remove any generated and non-modified scripts that were created by the metainit file with the name initname.
--purge
Only usable with --remove. Will remove the generated files even if modified.
