| History count
Is it possible to change the history counts ? Just see, when i type history command on my machine, i get around 1000 last typed commands.
Is it possible to change that count ?

| You can use the HISTSIZE command I know for bash shell... i.e. HISTSIZE=100 (or whatever value you want) and HISTFILESIZE to change the size of the actual history file.

root@server# histize

| echo $HISTSIZE
Check if the variable is set? and what the current value is.
or
change/add it on the file
~/.bash_profile

| root@server # cat ~/.bash_profile
HISTSIZE=100
Is this right ?
root@server# echo $HISTSIZE
1000
But, My history command shows 1051 commands now.
1044 histize
1045 cat /etc/issue
1046 echo $HISTSIZE
1047 vi ~/.bash_profile
1048 echo $HISTSIZE
1049 vi ~/.bash_profile
1050 cat ~/.bash_profile
1051 history

| thats the number of commands you have entered so far .
echo $HISTSIZE , shows u the value of commands that are stored in the file.
i.e 1000 for you.

Yes, 1000 for my server, i accept. But, how come it shows 1051 ? As it has been set for 1000, it show only the last 1000 commands rt ?

| If you have reached the limit of your history size (i.e., HISTSIZE is set to 1000 and you have 1000 commands in your history), then the older history entries will start rolling off of the top. (E.g., if the latest command in your history is 1012, then the earliest command in your history would be 13.) If you don't log out, then your history commands will continue to roll over. The history count does not get "reset" until after you log out. To truly see how many entries are in your history, type "history | wc -l".
Also, HISTSIZE only deals with commands during your current active session. You may want to set the HISTFILESIZE variable as well, just in case. Otherwise it might not save enough entries in the history file and may truncate the older commands.
