Archiving and compressing files is a good way to share them with others and to store them for later. Explore the tar and zip commands in this video.
- [Instructor] In the early days of computer systems…and still to a very large extent today,…data that needs to be archived for safekeeping…is recorded to backup tapes…and stored in a closet or basement…or ideally in a more secure and suitable location.…Tapes need files to be put together sequentially,…one after the other in a linear fashion…in order to be recorded onto the tape.…The output of putting files together like this…can be written to a tape drive…or it can be written to a single file on the disk.…These single files that contain a whole bunch…of files turn out to be very handy…for distributing software over the internet,…where you want your downloader…to have only one thing to go get,…rather than a whole handful of individual files.…
TAR files, short for Tape ARchive files,…are still incredibly common for software distribution…across Linux and macOS.…TAR files, unlike ZIP files,…don't offer compression themselves,…but there are ways to incorporate compression…into a TAR file which you may see…as you explore different software distribution styles.…
