zipper
A useful function to add to your ~/.bash_profile or ~/.bashrc file on macOS that automates custom zipping of files and folders. This function also checks to make sure that the resulting gzipped folder has the same date as the last date of modificationf or the folder.
Add in your path as a full shell script by copying all below and saving into a file named zipper located in your $PATH (e.g. /usr/bin), or copy and paste just the function into ~/.bash_profile or ~/.bashrc then restart Terminal.
#!/bin/sh
# zipper
## Usage: zipper "$1", where "$1" is a file or folder to gzip.
zipper () {
FILE_B_OUT="$(file -b "$1")";
if [[ "$FILE_B_OUT" = "directory" ]]; then
MY_DIR="$(basename "$1")";
echo "Directory name: ${MY_DIR}"
# make tarball:
echo "Creating gzipped tarball ${MY_DIR}.tar.gz ..."
tar -zcf "$MY_DIR".tar.gz "$MY_DIR" && touch -mt "$(stat -t %Y%m%d%H%M "$MY_DIR" | cut -d\ -f11 | sed 's/\"//g')" "$MY_DIR".tar.gz
echo "Done."
echo "..."
else
MY_FILE="$(basename "$1")";
echo "File name: ${MY_FILE}"
# make gzipped file, not keeping original:
MY_DATE="$(stat -t %Y%m%d%H%M "$MY_FILE" | cut -d\ -f11 | sed 's/\"//g')";
echo "File date: ${MY_DATE}"
echo "Creating gzipped file ${MY_FILE}.gz ..."
# This code keeps the original:
#gzip -c "$MY_FILE" > "$MY_FILE".gz && touch -mt "$MY_DATE" "$MY_FILE".gz
# This code does NOT keep the original (also exiting .gz file is overwritten, if present):
gzip -f "$MY_FILE" > "$MY_FILE".gz && touch -mt "$MY_DATE" "$MY_FILE".gz
echo "Done."
