If values other than JE are at the start of records that need to be removed, how are those records identified?
Do you always want to remove every line that starts with a J?
Do you always want to remove every line that starts with an uppercase alphabetic character?
Do you always want to remove every line that starts with a character that is not a numeric character?
Do you always want to remove the last line in every file you process?
Do you always want to remove every line that contains exactly two commas?
What operating system are you using?
What shell are you using?
What have you tried to solve this problem on your own?
we are using the following version of os version
Your question :
Do you always want to remove every line that contains exactly two commas?
Yes , but need not look all line for 2 commas, usual it will be found at the footer record. these record will not be available start and middle. so our approach is to look tail of the file and matches the pattern as less than 2 or 3 commas .
thanks for your quick response

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 :).

rm
RM(1) User Commands RM(1)NAME
rm - remove files or directories
SYNOPSIS
rm [OPTION]... [FILE]...
DESCRIPTION
This manual page documents the GNU version of rm. rm removes each specified file. By default, it does not remove directories.
If the -I or --interactive=once option is given, and there are more than three files or the -r, -R, or --recursive are given, then rm
prompts the user for whether to proceed with the entire operation. If the response is not affirmative, the entire command is aborted.
Otherwise, if a file is unwritable, standard input is a terminal, and the -f or --force option is not given, or the -i or --interac-
tive=always option is given, rm prompts the user for whether to remove the file. If the response is not affirmative, the file is skipped.
OPTIONS
Remove (unlink) the FILE(s).
-f, --force
ignore nonexistent files and arguments, never prompt
-i prompt before every removal
-I prompt once before removing more than three files, or when removing recursively; less intrusive than -i, while still giving protec-
tion against most mistakes
--interactive[=WHEN]
prompt according to WHEN: never, once (-I), or always (-i); without WHEN, prompt always
--one-file-system
when removing a hierarchy recursively, skip any directory that is on a file system different from that of the corresponding command
line argument
--no-preserve-root
do not treat '/' specially
--preserve-root
do not remove '/' (default)
-r, -R, --recursive
remove directories and their contents recursively
-d, --dir
remove empty directories
-v, --verbose
explain what is being done
--help display this help and exit
--version
output version information and exit
By default, rm does not remove directories. Use the --recursive (-r or -R) option to remove each listed directory, too, along with all of
its contents.
To remove a file whose name starts with a '-', for example '-foo', use one of these commands:
rm -- -foo
rm ./-foo
Note that if you use rm to remove a file, it might be possible to recover some of its contents, given sufficient expertise and/or time.
For greater assurance that the contents are truly unrecoverable, consider using shred.
