grep - search text in gzipped file

In this short article, we would like to show how to find any text in gzipped text file (*.gz files) using grep command in Bash.

Quick solution (run the following command):

zgrep 'text to find here ...' /path/to/log.gz

Where: zgrep calls grep with *.gz files reading support.

Orher examples

1. Searching with case insensitive

zgrep -i 'text to find here ...' /path/to/log.gz

Where:

• -i or --ignore-case causes text matching with case insensitive ignoring.

2. Searching with regular expressions

Below command example matches digits in log.gz file.

zgrep -E '\d+' /path/to/log.gz

Where:

• -E runs searching in regular expression mode,
• '\d+' should be changed to any regular expression.
