Extracting Archived/Compressed Files

On the Grid, there are two sets of system-wide tools for extracting files from an archive/compressed file: unzip and gunzip.

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
