jq

jq - commandline JSON processor, to visualize json output in a readable way

Example unformated text-output: 

cat test
[{"target_name":"mytarget","message":"Successfully processed","action_success":true}]

Output formated by piping in jq via command: 

cat test | jq '.[] | select(.target_name == "mytarget" and .message == "Successfully processed"  and .action_success = "true")'
{
  "target_name": "mytarget",
  "message": "Successfully processed",
  "action_success": true
}

Manipulating Strings

https://tldp.org/LDP/abs/html/string-manipulation.html

Examples: 

Ueb="String1_String2_String3"

Remove 1. string:
Ueb1=${Ueb#*_}
# echo $Ueb1
String2_String3

Keep 1. string:
Ueb1=${Ueb%%_*}
# echo $Ueb1
String1

Remove last string:
Ueb1=${Ueb%_*}
# echo $Ueb1
String1_String2

Keep last string:
Ueb1=${Ueb##*_}
# echo $Ueb1
String3

Another example: 

# echo ${TEST:-Foo}
Foo
# echo $TEST
# echo ${TEST:=Foo}
Foo
# echo $TEST
Foo

awk

Examples: 

# echo "somestring.or.url.com somestring1.or.url1.com" | awk '{print $1".to.add.anotherstring "$2".and.one.more"}'
somestring.or.url.com.to.add.anotherstring somestring1.or.url1.com.and.one.more
awk -F: /my-user/'{print $3}' /etc/passwd                                                                      #getting uid of user "my-user"
java -version 2>&1 | awk -F '-' 'NR==2 {print $2}'                                                             #searching for "-" in string and cut all in between, but just from line 2 (NR==2) as the result has 3 lines
ifconfig -a | awk '/inet 10/{print $2}'                                                                        #getting IP adress starting with "inet 10"
echo "somestring1 somestring2" | awk '{print $1,$2}'
