Grep command output displays highlighted characters

Grep command output displays highlighted characters

After the grep command is executed, the "-- color = auto" parameter can be added to the output color of the terminal.

The other two methods are as follows:

1. Set environment variables:

Export GREP_OPTIONS = "-- color = auto"

2. Modify. bashrc

Alias grep and set it with alias. My system has been written but commented out,

Now open him and see 84 rows:

84 alias grep = 'grep -- color = auto'

85 # alias fgrep = 'fgrep -- color = auto'

86 # alias egrep = 'egrep -- color = auto'

In this way, the standard output after grep execution marks the matching file as a color.

[Root @ mode etc] # grep allowed_host/usr/local/nagios/etc/nrpe. cfg

Allowed_hosts = 172.30.71.20

If the configuration is ineffective, modify the secureCRT settings:

Location:

Options-> Global options-> General-> Default session-> Edit Default Settings-> Terminal->

Appearance-> Font

Option-Global Options-General-default session-edit default settings-simulation (terminal set to Linux and use color schemes)-appearance (font Lucida Console 10pt, character encoding UTF-8)

Close the current session after setting. Open it again.
