##grep

ref:

##Count Occurrence: `-c`

TEXT

$ cat example.txt | grep -c good
2

##Get Context: `-C`

Set --context=0 to print that line alone

TEXT

$ cat example.txt | grep --context=0 "good luck"
good luck

Set --context=1 to print 1 line below and 1 line above

TEXT

$ cat example.txt | grep --context=1 "good luck"
hello world
good luck
good day

or use -C 1

#awk

##tldr

A versatile programming language for working on files. More information: .

Print the fifth column (a.k.a. field) in a space-separated file:

TEXT

awk '{print $5}' path/to/file

Print the second column of the lines containing “foo” in a space-separated file:

TEXT

awk '/foo/ {print $2}' path/to/file

Print the last column of each line in a file, using a comma (instead of space) as a field separator:

#sed

##tldr

sed -i "[range]s/[patern]/[replacement]/[options]" file_*
sed -i "2,5s|[patern]|[replacement]|[options]" file_*

###Search for text

Search for a string and only print the lines that were matched

$ sed -n '/hello/p' file.txt

Case insensitive search

$ sed -n '/hello/Ip' file.txt

###Sed Usage

Syntax

shell

$ sed [options] command [input-file]

With pipeline

$ cat report.txt | sed 's/Nick/John/g'

$ echo '123abc' | sed 's/[0-9]+//g'

###Option Examples

Option	Example	Description
`-i`	sed -ibak ’s/On/Off/’ php.ini	Backup and modify input file directly
`-E`	sed -E ’s/[0-9]+//g’ input-file	Use extended regular expressions
`-n`	sed -n ‘3 p’ config.conf	Suppress default pattern space printing
`-f`	sed -f script.sed config.conf	Execute sed script file
`-e`	sed -e ‘command1’ -e ‘command2’ input-file	Execute multiple sed commands

###Multiple commands

$ echo "hello world" | sed -e 's/h/H/g' -e 's/w/W/g'
Hello World

Use -e to execute multiple sed commands
