Terminal - All commands - 5 results
less -X /var/log/insecure

From the manpage:

man less

-X or --no-init

Disables sending the termcap initialization and deinitialization strings to the terminal. This is sometimes desirable if the deinitialization string does something unnecessary, like clearing the screen.

Bonus:

If you want to clear the screen after viewing a file this way that had sensitive information, hit or just type clear. Since is readily available, I don't know why less bothers to automatically clear. If you're viewing the file at all, chances are you want to see the output from it after you quit.

sed '/INSERT INTO `unwanted_table`/d' mydb.sql > reduced.sql

User: sudopeople
Functions: sed

Starting with a large MySQL dump file (*.sql) remove any lines that have inserts for the specified table. Sometimes one or two tables are very large and uneeded, eg. log tables. To exclude multiple tables you can get fancy with sed, or just run the command again on subsequently generated files.

netstat -n | grep ESTAB |grep :80 | tee /dev/stderr | wc -l

Functions: grep netstat tee wc
0

Summarize established connections after netstat output.

Using tee and /dev/stderr you can send one command output to terminal before executing wc so you can summarize at the bottom of the output.
