Shell script and mv directory creates extra character but not when run on cmd line

Question

I need to rename a directory in a crontab job so created bash file to run the script that that will move the folder prior to running mongodump command.
When I run the command directory on the command line the directory is moved and renamed without any extra characters

When I run the move.sh that directory is moved but with an trailing ? at the end of the directory name. Rm -R /change071105^M also appear.. Any insight is appreciated

Checked move.sh for extra character.

Directory was renamed and all files appeared.

Created a move.sh with:

Resume of mv in script renames directory as: change071105? not the expected change071115

Ran command at the command line to confirm

mv /mongo_backup/change /mongo_backup/change$(date --date='1 day ago' +'%m%d%y')

also checked move.sh for extra spaces ..

 #!/bin/bash
    dd=$(date --date='1 day ago' +'%m%d%y')
    mv -v "/mongo_backup/change" "/mongo_backup/change$dd"
    #mv /mongo_backup/change /mongo_backup/change$(date --date='1 day ago' +'%m%d%y')

Does your script file have Windows line endings but you're not running it on Windows? — Shawn, Jul 16 '19 at 13:28

Run `bash -x yourscript` to run it with logging of exactly what it executes. If you have DOS newlines, they'll show up as `$'...\r'` — Charles Duffy, Jul 16 '19 at 13:49

you should perform dos2unix. ^M this refers to the line ending from windows file copied to unix environment — yoga, Jul 16 '19 at 14:48

Issue was created in notepad on a windows machine and extra characters when creating scripts: added mv -v and when running script >sh the \r appeared in output

Refined search and below fixed this issue sed -i 's/\r$//' scriptname.sh
