Zcat<\/strong>\u00a0is a command line utility for viewing the contents of a compressed file without literally uncompressing it. It expands a compressed file to standard output allowing you to have a look at its contents. In addition, zcat is identical to running\u00a0gunzip -c<\/strong>\u00a0command. In this guide, we will explain zcat command examples for beginners.<\/p>\n

1.<\/strong>\u00a0The first example shows how to view contents of a normal file using\u00a0cat command<\/a>, compress it using\u00a0gzip command<\/strong>\u00a0and view the contents of the zipped file using\u00a0zcat<\/strong>\u00a0as shown.<\/p>\n

$ cat users.list \r\n$ gzip users.list\r\n$ zcat users.list.gz\r\n<\/pre>\n
\n
\"View<\/a><\/p>\n
View Compressed File Contents in Linux<\/p>\n<\/div>\n
2.<\/strong>\u00a0To view multiple compressed files, use the following command with filenames as shown.<\/p>\n
$ zcat users.list.gz apps.list.gz\r\n<\/pre>\n
\n
\"View<\/a><\/p>\n
View Multiple Compressed Files Content in Linux<\/p>\n<\/div>\n
3.<\/strong>\u00a0To view contents of normal files use the\u00a0-f<\/code>\u00a0flag, similar to\u00a0cat command<\/a>, for example.<\/p>\n
$ zcat -f users.list\r\n<\/pre>\n
\n
\"View<\/a><\/p>\n
View Linux File Contents<\/p>\n<\/div>\n
4.<\/strong>\u00a0To enable pagination, you can use the\u00a0more<\/strong>\u00a0and\u00a0less<\/strong>\u00a0commands as shown (Also read:\u00a0Why \u2018less\u2019 is Faster Than \u2018more\u2019 Command in Linux<\/a>).<\/p>\n
$ zcat users.list.gz | more\r\n$ zcat users.list.gz | less\r\n<\/pre>\n
5.<\/strong>\u00a0To get the properties (compressed size, uncompressed size, ratio \u2013 compression ratio (0.0% if unknown), uncompressed_name (name of the uncompressed file) of a compressed file, use the\u00a0-l<\/code>\u00a0flag.<\/p>\n
$ zcat -l users.list.gz  \r\n<\/pre>\n
\n
\"View<\/a><\/p>\n
View Compressed File Properties in Linux<\/p>\n<\/div>\n
6.<\/strong>\u00a0To suppress all warnings, use the\u00a0-q<\/code>\u00a0flag as shown.<\/p>\n
$ zcat -q users.list.gz\r\n<\/pre>\n
For more information, see the\u00a0zcat<\/strong>\u00a0man page.<\/p>\n
$ man zcat\r\n<\/pre>\n
