Outputting Errors to a Log file

Good Morning,

Every so often, I have copy scripts that to don't complete, but I don't immediately know why. It usually ends up being a permissions issue or a length issue.

The scripts edit a log file, so I'd like to include any copy errors/issues in that file to check if the copies ran into issues. I'm thinking:
Code:
cp -R /dir/dir/dir /dir2/dir2/dir2 2>&1 | printf /dir/dir/logfile

Will this work and/or is there something better? Will it work even if the script fails to complete the copy?

NAME
shtool-mkshadow - GNU shtool create shadow tree using symlinks SYNOPSIS
shtool mkshadow [-v|--verbose] [-t|--trace] [-a|--all] src-dir dst-dir DESCRIPTION
This command creates a shadow tree of src-dir under dst-dir by recreating the directory hierarchy of src-dir under dst-dir and by creating the files of src-dir by linking them into the corresponding directories under dst-dir via symbolic links. When src-dir can be reached via relative paths from dst-dir, relative symbolic links are used, too. This high-level functionality is originally designed for developers to create copies of source trees. OPTIONS
The following command line options are available. -v, --verbose Display some processing information. -t, --trace Enable the output of the essential shell commands which are executed. -a, --all Really shadow all files and directories in src-dir. Default is to skip CVS related files and directories, backup files, object files, etc. EXAMPLE
# shell script shtool mkshadow -v -a . /tmp/shadow HISTORY
The GNU shtool mkshadow command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1998 for Apache. It was later revised and taken over into GNU shtool. SEE ALSO
shtool(1), ln(1). 18-Jul-2008 shtool 2.0.8 SHTOOL-MKSHADOW.TMP(1)
