====Terminator=====

Personalized terminator settings: 

  shift+F10                                                 #Preferences (if "PuTTY style paste" is active)
  strg+shift+c                                              #copy
  strg+alt+h                                                #split horizontally
  strg+alt+v                                                #split vertically
  strg+alt+m                                                #multiplex (groupalltoggle)
  Terminator -> Preferences -> Profiles -> Scrolling        #set lines of scollback (infinite or to amount of lines)

====jq====

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

Example unformated text-output:

  cat test

<code>
[{"target_name":"mytarget","message":"Successfully processed","action_success":true}]
</code>

Output formated by piping in jq via command:

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

<code>
{
  "target_name": "mytarget",
  "message": "Successfully processed",
  "action_success": true
}
</code>

====Manipulating Strings====

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

Examples:

<code>
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
</code>

Another example:
<code>
# echo ${TEST:-Foo}
Foo
# echo $TEST
# echo ${TEST:=Foo}
Foo
# echo $TEST
Foo
</code>

====awk====
Examples:
<code>
# 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
</code>

  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}'
