Compressing and Extracting Files

================

At this time, only one file can be downloaded from the RCP at a time. Should you need to download more than one file, one option is to compress them (e.g., zip) into one folder for download. Additionally, you may need to extract compressed files you uploaded onto the RCP. This tutorial provides information on how to use system-wide tools to compress and extract files.

These commands can be issued in the terminal of your research software of choice.

zip

The zip command can be used to zip one or more files into a ZIP folder.

To zip one file:

Command	Example
zip ZIPFILE FILE	zip data.zip data.R

To zip a folder:

Command	Example
zip –r ZIPFOLDER FOLDER/	zip –R datafolder.zip datafolder/

unzip

The unzip command can be used to extract from common archive formats such as ZIP and RAR.

To extract all contents to the current directory:

Command	Example
unzip FILE	unzip data.zip

To only extract all contents to the current directory within a specific subfolder of the archive:

Command	Example
unzip FILE FILENOEXTENSION/SUBFOLDER/*	unzip data.zip data/2005/*

To extract contents to a specific folder:

Command	Example
unzip FILE -d DESTINATION	unzip ziptest.zip -d '/export/home/dor/jharvard'

gunzip

gunzip is meant to be used on files ending with .gz or .z.

To extract a file into the current directory and not save the original compressed file:

Command	Example
gunzip FILE	gunzip yourdocument.docx.gz

To extract a file into the current directory and keep both the compressed and decompressed file:

Command	Example
gunzip < ORIGINALFILE > EXTRACTEDFILE	gunzip < yourdocument.docx.gz > yourdocument.docx
