How to customize user Korn Shell env in Solaris 10

---

You need the following files in users home directory :
- .exrc
- .kshrc
- .profile

If you want Solaris10 for your username to track history commands you have to create in your home directory .sh_history file.
touch $HOME/.sh_history


Content of .exrc

---

set nu
set showmode



Content of .kshrc

---

TERM=ansi;export TERM
SHELL=/usr/bin/ksh;export SHELL
PS1="$LOGNAME@`uname -n` \$PWD $";export PS1
PATH=$PATH:/usr/sbin:/usr/bin:/usr;export PATH
set -o vi
stty erase ^H
# banner Hello Sys Admin!
function num { who | wc -l; }
#
#
#
function list { ls -la | wc -l; }
#
#
function cluster { cat /var/sadm/system/admin/CLUSTER; }
#
function dow {
if [[ -z $1 ]] # Check for existence of option on command line
then
date +%A # If not, display day of week on stdout
return 0 # Return success
fi
case $1 in
-s) WEEKDAY=$(date +%A);; # If –s is used, set variable WEEKDAY
*) print “Format is dow [-s]” # Anything else is an error
return 1;; # Return failure
esac
}



Content of .profile

ENV=/home/`$LOGNAME`/.kshrc;export ENV
# ksh;exit ---> this line if your default shell is sth different then ksh



Displaying history of commands

---

There is nice feature of SHELL in Slaris10 called history of typed commands. It works in cooperation with data file /$HOME/$LOGNAME/.sh_history.
You can display history of recently typed commands :
history
1 ls -la
2 history
3 df -h
4 g
5 history
6 format
7 history

You can recall whatever line you want from the output of history command by issuing :
r 3
It means recall third line.

The Korn Shell stores command history in a file specified by HISTFILE variable. The default is the ~/.sh_history file.You can use HISTSIZE variable to specify the number of commands to store in this buffer. If this variable is not set, then shell stores the most recent 128 cmds.
By default historycommand displays the last 16 commands to the stdout.

To display commands without line numbers :
history -n
To display the current command and 4 cmds preceding it :
history -4
To display the history list in reverse order :
history -r
To display the mos recent cd cmd to the most recent datecmd :
history cd ls
