>Usage
gzip is a command-line utility used to compress
files using the gzip compression algorithm, which reduces the file size for easier storage or transfer.
>Synopsis
>Options
-c
to stdout: Outputs the compressed data to the standard output (stdout) rather than modifying the original file.
Example 1:
-zsh
gzip -c file.txt > file.txt.gz
the file file.txt is compressed and redirected to
a new file file.txt.gz without modifying the original file
-k
keep original: When you use this option, gzip compresses the file but keeps the original one instead of deleting it after compression.
Example 2:
-zsh
gzip -k file.txt
after the execution you'll have both text.txt and
text.txt.gz (the compressed file)
-r
recursiv: With this option gzip will compress all files within a directory and its subdirectories recursively. Useful to compress multiple files in a directory without needing to specify each file individually
Example 3:
-zsh
gzip -r dir/
compress all files in the directory/subdirectories and replace each file with the compressed version
-l
.gz),
such as original size, compressed size, compression ratio,...
-S
suffix: Allows to specify a costum suffix for the compressed file instead of the default one (.gz), this will not affect the compression
Example 4:
-zsh
gzip -S .zip file.txt
the argument after -S will replace the default .gz suffix
-t
.gz file without decompressing it.
If the file is valid it will generate no output.
