Shell Programming and Scripting

Dear Experts,
Need your help.
Typically we use "grep" to search and display a pattern in a txt file.
However, here what we want is, we want to grep a line which contains 4 words any where in a line.

For example.
File has 10,000,000 lines in it out of which there is a particular line which has following four words randomly palced in the line with randon sequence.

Lakmay, lorial, nivia and lotus.

That line we need to grep.

Please help.

Chain the greps together:

Code:

grep Lakmay bigfile | grep lorial | grep nivia | grep lotus

or use awk:

Code:

awk '/Lakmay/&&/lorial/&&/nivia/&&/lotus/' bigfile
