OK. We're dealing with empty .bam and .bam.bai files, so we won't be destroying your data no matter what we do here.

When I recreated your file hierarchy on my system, change the first line of Peasant's code from:

Code:

#!/usr/bin/bash

to:

Code:

#!/bin/bash

and ran his code the results looked promising. So, I change the lines:

Code:

		echo "mv ${FLN} ${FLN/$FLNSUB}"
 ... ... ...
echo "mv $RDIR ${TRIMSTR}"

in his code to:

Code:

		mv "${FLN}" "${FLN/$FLNSUB}"
	done
	# Now we shall rename the folder, after files inside have been renamed.
	mv "$RDIR" "${TRIMSTR}"

and reran the script. Afterwards, I ran an ls on the resulting file hierarchy and got:

Code:

$ ls -lR home
total 0
drwxr-xr-x  3 dwc  staff  96 Mar 17 08:51 cmccabe

home/cmccabe:
total 0
drwxr-xr-x  3 dwc  staff  96 Mar 17 08:53 rename

home/cmccabe/rename:
total 0
drwxr-xr-x  6 dwc  staff  192 Mar 17 08:53 R_2019_01_30_14_24_53_user_S5-0271-95

home/cmccabe/rename/R_2019_01_30_14_24_53_user_S5-0271-95:
total 0
-rw-r--r--  1 dwc  staff  0 Mar 17 08:51 xxx_011_xx00_xxx.bam
-rw-r--r--  1 dwc  staff  0 Mar 17 08:51 xxx_011_xx00_xxx.bam.bai
-rw-r--r--  1 dwc  staff  0 Mar 17 08:51 xxx_013_xx00_xxx.bam
-rw-r--r--  1 dwc  staff  0 Mar 17 08:51 xxx_013_xx00_xxx.bam.bai
$

which looks exactly like what I thought you were trying to produce.

I guess Peasant and I both thought that you knew how to rearrange the quotes on his echo commands to get working mv commands.

If you try his code again with the mv commands changed to match what I have suggested above, do you get what you want?
