VIM vs EMACS

Comparison between VIM and EMACS commands.
In EMACS - C means "Control" key and M means "Alt" key.
In VIM - most of the commands are done in escape mode unless specifically mentioned.

Traversing current command and command history

In BASH, by default emacs mode is enabled. (set -o emacs)

Traversing the Command
ctrl+f to go forward
ctrl+b to go backward
ctrl+a to go start of the line
ctrl+e to go end of the line
ctrl+p to go previous command
ctrl+n to go next command
ctrl+w to delete word backward
ctrl+k to delete from cursor to end of line
ctrl+i to search for previous commands
ctrl+d to delete letter under cursor
ctrl+l to clear the screen
ctrl+r increment search backwards, use ctrl+r to go next.

Switching between directories
"cd -" is used to switch between directories current $PWD and  $OLDPWD (where PWD is current working directory and OLDPWD is previous working directory).

cd -

for example - 
# Current directory - /home/rajashekr/Downloads
rajashekr@ubuntu:~/Downloads$ pwd
/home/rajashekr/Downloads

# Going to home directory -
rajashekr@ubuntu:~/Downloads$ cd

# To go to previous directory
rajashekr@ubuntu:~$ cd -
/home/rajashekr/Downloads

use cd- to go back to previous director

To execute previous commands
In general, you can navigate thru history by using up and down arrows
Using "!" to execute previous commands.

!<previous-command-starting-letters>

For example -
rajashekr@ubuntu:~/Downloads$ find . -name "*.txt"
./vmware-tools-distrib/doc/open_source_licenses.txt

rajashekr@ubuntu:~/Downloads$ ls
VMwareTools-8.4.7-416484.tar.gz  vmware-tools-distrib

rajashekr@ubuntu:~/Downloads$ vi test.txt

# execute previous command that start with fi
rajashekr@ubuntu:~/Downloads$ !fi
find . -name "*.txt"
./vmware-tools-distrib/doc/open_source_licenses.txt
./test.txt

Other way is to have number of the command in history

!<number-of-the-command-in-history>

$ history | grep -i find
   66  find . -name "*.java"
   67  find . -name "*.java" | grep -i paymentsummary_005fordersummary_005fwp_005ffg_jsp.java

$ !67
find . -name "*.java" | grep -i paymentsummary_005fordersummary_005fwp_005ffg_jsp.java

Tip: You can use alias.
For example: alias gh='history | grep '

$ gh find
   66  find . -name "*.java"
   67  find . -name "*.java" | grep -i paymentsummary_005fordersummary_005fwp_005ffg_jsp.java

Search previous commands with matching pattern

!?<previous-command-substring>

For example:
$ find . -name "*.txt"
./.#log.txt
./log.txt

$ find . -name "*.jsp"

$!?txt
find . -name "*.txt"
./.#log.txt
./log.txt

Use ctrl+r increment search backwards, use ctrl+r to go next.

Passing all previous arguments to current command

!*

For example -
rajashekr@ubuntu:~/Downloads$ echo test > test.txt
rajashekr@ubuntu:~/Downloads$ more test.txt
test
rajashekr@ubuntu:~/Downloads$ cat !*
cat test.txt
test

Another example :
$ touch sample.txt
$ mv !* !*.bak
mv sample.txt sample.txt.bak 

Passing only previous command last argument to current command

!$

Example:
$ echo test1 test2
test1 test2
echo !$
echo test2
test2Substitue previous command

!!

For example:
$ find . -name "web.xml"
./actint.war/WEB-INF/web.xml
./atg_admin.war/WEB-INF/web.xml
./atg_bootstrap.war/WEB-INF/web.xml

$ grep -i atg.filter.dspjsp.PageFilter `!!`
grep -i atg.filter.dspjsp.PageFilter `find . -name "web.xml"`
./actint.war/WEB-INF/web.xml:        <filter-class>atg.filter.dspjsp.PageFilter</filter-class>
./atg_bootstrap.war/WEB-INF/web.xml:<filter-class>atg.filter.dspjsp.PageFilter</filter-class>
./common.war/WEB-INF/web.xml:        <filter-class>atg.filter.dspjsp.PageFilter</filter-class>

Substitute substring in previous command

!!:s/old/new/
or
^old^new

Example:
$echo test1
test1
$!!:s/test1/test2/
echo test2
test2
$ ^test2^test1
echo test1
test1

!!:gs/old/new/ does the same as above globally

!! is previous command
!!:0 is previous command first word
!!:1 is previous command second word

!# current command
!#:0 current command first word
mkdir test1; cd !#:1 to create directory and cd to that directory
for above !! and !# use :h for head of the word and :t for the tail of the word

To switch to vi mode
set -o vi - to have vi mode
Go through below commands to use vi keys

In ksh - Korn Shell
Make sure that you have
To enable "vi" key commands
set -o vi
To enable tab completion
set -o viraw

To navigate history

<Esc> and then use j,k to go up and down respectively

To edit current command

Use <Esc> use h,l to go previous and next letter.
Use "x" to delete current letter,
Use "r" to replace current letter.

To search previous commands

<Esc>/awk - to find previous commands which has awk in it
"n" - to go next command
"N" - to go previous command

To use "vi" to edit current buffer

<Esc>v to open current command buffer and
"wq" to execute command.

Please note that you can also set "set -o vi" in bash too and have above features.

How to find the exact instance with session id in Weblogic cluster using curl or lynx

Suppose we have 90 weblogic app server instances running behind the load balancers and AKAMAI.
If a user faces an error/exception in one scenario. If we have the user session id (For example: xGGwM2Hpq0lhCr!-1529204333)
Note: For each server we will have jvm id. The part after delimeter !- is jvmid or serverid which will not be changed until server restarts.

To find the exact server so that we directly jump to exact logs. Instead of going through all 90 instances.
Using lynx - findhost.sh

#!/bin/bash
# Iterate through each host
for i in {20..109};
do
  # get jvmid or server id the part after delimeter !- in session id
  jvmid=$(lynx -dump -head http://host$i:7001/business/ | grep -i session  | sed 's/^.*!\|^.*-\|;.*//g')
  echo "p2pre1c$i : $jvmid"
done

or
Using curl - findhost.sh

#!/bin/bash
# Iterate through each host
for i in {20..109};
do
  # get jvmid or server id the part after delimeter !- in session id
  jvmid=$(curl --head --silent http://host$i:7001/business/ | grep -i session  | sed 's/^.*!\|^.*-\|;.*//g')
  echo "p2pre1c$i : $jvmid"
done

Explanation:
curl --head  and lynx -dump -head
will dump the headers which will have session id
For example:
# lynx -dump -head http://host20:7001/business/

Few commands to know about solaris box

Mostly Solaris is used as production server since it is more robust.

To know if the solaris running in 32 or 64 bit mode
The isainfo utility can  answer are  whether  64-bit  applications are supported, or whether
the running kernel uses 32-bit or 64-bit device drivers.

$ isainfo -v

64-bit sparcv9 applications
        vis2 vis
32-bit sparc applications
        vis2 vis v8plus div32 mul32

if you get only 32-bit then it is running in 32 bit mode
if you get both 64-bit and 32-bit then it is running in 64 bit mode

The uname utility prints information about the current  system on the standard output.

$ uname -X

System = SunOS
Node = bsdevprem01
Release = 5.10
KernelID = Generic_127111-08
Machine = sun4u
BusType = <unknown>
Serial = <unknown>
Users = <unknown>
OEM# = 0
Origin# = 1
NumCPU = 2

To know the installed JVM is capable of running 64-bit version

$ java -d64 -version

java version "1.5.0_15"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_15-b04)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_15-b04, mixed mode)

if not 64 bit capable you will get some message like

This Java instance does not support a 64-bit JVM. Please install the desired version.

To know how long the serer is up
