Hi friends,
I tried with "UP" Keys but I am getting some special charaters only,
Is there any method to get the previous commands?

Kindly advice

did you try the 'history' command? It is typically enabled in Solaris.

The default shell (/bin/sh) which is the original Bourne shell doesn't has this feature.
You need to switch to a shell providing command history, like bash, ksh or zsh.

I suspect you are logged in as root. This is a very bad practice, as you can easily break the system with a mistake.

Create a user account and stick to it.

Here are some commands that will create a user account for you with a shell you are familiar with:

Code:

useradd -m -k /etc/skel -P "Primary Administrator" -d /export/home/kcarun -s /bin/bash kcarun
passwd kcarun
# enter your new password here
echo "* -fstype=lofs :/export/home/&" >> /etc/auto_home
/usr/sbin/automount -v
usermod -d /home/kcarun kcarun

After you have created an ordinary account (which has bash shell), you can use arrow up, and also write "history" and you will get a list of old commands. Like:

1 ls -la
2 cat kebap.txt
3 cat orvar.txt

then you can write

!ca

and press enter, then it will execute the latest command that started with "ca" which is "cat orvar.txt" in this case.

Thaks for your advice kebabbert,

& jlliagre you are 100% right i am using only root login for my past 1 year in Debian & now that is continuing in SUN also..Thanking you for leading me to the right direction,

Arun
( Yesterday i just typed #bash(accidently) in command prompt , after that i am getting the history)

jlliagre,

I created the user and , read the man pages to understand the options (like -m,-P),but still some more doubts!

1) -k /etc/skel is to copy the profile, what are the advantage of this?

2) echo "* -fstype=lofs :/export/home/&" >> /etc/auto_home ,

This command appended a line in /etc/auto_home , but for other uses ,we are manually updating this line, for this user(kcarun) the line is differ from others?

sindhu localhost:/export/home/sindhu
guest2 localhost:/export/home/guest2
joshy 127.0.0.1:/export/home/joshy
* -fstype=lofs :/export/home/&
bash-3.00$

3)"/usr/sbin/automount -v" is used for what purpose?

Kindly Advice

Well, it copies the profile files, no big deal.

The line I append is equivalent to the one you had with these differences:
- lofs is faster than nfs
- it works for all users, no need to specify one line for each one.

It reloads the settings.

thanks jlliagre for the help

kebabbert · 08-03-2007, 02:44 AM

(The profile files are used to setup the environment (PATH, etc) once and for all for each new user, and then every new user will use the environment you just setup. If you dont do this, every user has to setup for instance, the PATH variable)

kcarun · 08-03-2007, 01:01 PM

Ok kebabbert,

now i am using my new id for login,

In debian by editing "/etc/sudoers " file we can give permisson for executing commands ,

that arrangement is not in Solaris?

If you followed the instructions I posted, you are granted the "Primary Administrator" role.
You can run any command as root by prefixing it by "pfexec".

kcarun · 08-04-2007, 08:51 AM

HI jlliagre,

I tried pfexec method, but it is not working.

Quote:

bash-3.00$ who am i
kcarun pts/4 Aug 4 18:59 (:0.0)
bash-3.00$ pfexec ifconfig
ifconfig: Command not found
bash-3.00$

At the time of creating this user i am suspectingthat I changed the below selected part as "Primary Admin", that is only a description of the user or it is the critical part of the command?

Quote:

useradd -m -k /etc/skel -P "Primary Administrator" -d /export/home/kcarun -s /bin/bash kcarun

How can I findout the rights of the user(kcarun) ?

reg

Your test didn't demonstrate it worked or not but just that ifconfig isn't in the PATH. You should have run "pfexec /usr/sbin/ifconfig ..." instead.
A simple test to check your settings:

Code:

$ id
uid=10000(jlliagre) gid=10000(jlliagre)
$ pfexec id
uid=0(root) gid=0(root)

It is indeed critical.

The profiles precisely:

Code:

$ profiles
Primary Administrator
Basic Solaris User
All

And to fix them if you misspelt Administrator:

Code:

# /usr/sbin/usermod -P "Primary Administrator" kcarun
