UNIX for Dummies Questions & Answers

Hello All,
Many developers in our company use same application account to log in Linux Box for code development, how can i redirect my log in shell history to a different file to avoid history being shown to others or accidentally execute the same command which i or others executed?

Thank you.

How history is handled varies from shell to shell (and you didn't bother telling us which shell you're using).

Look at the man page for your shell and search for the description on that page for a description of the HISTFILE variable. (Note that changing HISTFILE might not affect the current shell execution environment; but if you export it and exec a new shell, it should be effective in that environment.)

If you don't find HISTFILE, look for history file or history to find out how to set the history file for your shell.

My bad we log in to CSH and then change the shell to KSH and do the coding. I looked at the man page of HISTORY it talks more about events and other stuff, do not understand how to change the behavior, could you please throw some light.

Thank you.

I didn't say to look at the HISTORY man page; I said to look at the man page for your shell (ksh in this case) and look for the HIStORY environment variable on that man page.

If you're users are logging in to an environment running csh and they manually invoke ksh, the simple thing to do is something like the following while you are still in csh:

Code:

setenv HISTFILE=$HOME/.ksh_history.username
exec ksh

where username is the real name of the user logging in to this shared environment; not the shared account name everyone is logging into on this machine. That will give each user a separate history file (and keep track of the commands that user has used across logins).

Thank you it worked. I am trying to put the same/below in a file .vimrc and sourced the file, however when i vi the file it is not showing color scheme i wanted and i have to explicitly define the color scheme after i vi the file.Is there any way i can make this work? i am using KSH.

.vim.rc

Code:

set syntax on
set colorscheme murphy
set hlsearch on
HISTFILE=/tmp/.ksh_history.$$

Sourcing
. ./.vim.rc
