发帖数: 132 | 9 that's definitely an alternative to tunnel xwindow traffic.
But since hundreds of users are used to telnet, and it's
expensive
to spend dollars for hundreds of licenses of ssh client
still looking for cheap solution.
there should be a simple script to identify whether it is
console login or not, if not, then decide where the user is
from, then define DISPLAY variable.
Any ideas? |

发帖数: 1879 | 10 There is a way, but not very good.
1. get current tty
2. finger -l username | grep tty | cut fromremotesite
3. check if it is the console, setenv
p.s. last is not as good as finger. |
|
h**h
发帖数: 132 | 11 This doesn't work either, since most unix servers disable
finger server
well, the worst case is to write a shell script
to
1> who -m
user pts/9 Oct 20 17:35 (10.10.10.10)
2> parse info between ($REMOTEHOST)
3> See if it is from console or not
4> export DISPLAY=$REMOTEHOST:0.0
put that in .profile or .login? |

发帖数: 165 | 13 You need to make sure the bash is installed in your
$HOME/bin/bash (I am sure you know).
If your system have already bash available (I know you have
'cause you can type bash after login), normally it will be
under /bin
Add following lines to your .profile and it will do the job
for you.
if [ -x /bin/bash ]; then
exec /bin/bash
fi
You can change to ksh & csh by this way as well. |
|
c*****t
发帖数: 1879 | 14 You should man csh/ksh/tcsh, depending on the shell
used. There, hit '/' key to do a search on 'FILE'.
That should immediately bring you to the files used.
Usually, the man page will tell you the exact order
of the files being processed. |

发帖数: 87 | 15 for csh, tcsh, .cshrc and .login are executed
for ksh, bsh, bash, .profile and .login are executed.
But I think bwang's question has some ambiguity. If he just wants to execute
some command once in one session, like xhost +font under an X environment,
then he shouldn't add entries in these startup files.
instead he should check what kind of session manager he is using and modify
the corresponding script, like .xsession and so on. |

发帖数: 165 | 22 Normally /bin is a link to /usr/bin and ksh & sh are default
for Solaris. Only
when you need to use CSH, you need to edit /etc/shells.
When we have a root account, why should be add another one
to do the same job.
I guess whether to change root shell depends on personal
preference. At one
point I read a faq called 'root faq' and it is still
probably searchable on net.
I changed the root shell for myself because I have to do
many things as root
and it just doesn't make sense to work with sh mos |

发帖数: 497 | 31 some Unix allow you change yourself using chsh command
In some ksh, ESC key will active your command line editor(vi for example),
you can using vi command key stroke to go back/forward and do any editing.
ESC twice will do the complete command line with filename |

发帖数: 153 | 34 bash has similar features too. and some Ksh too, but the key-stroke is
different, you need to press ESC twice to into command line editor,
or Esc once to complete commmand line(i.e. auto complete the file name) |

发帖数: 165 | 38 Using ksh, writing a script to parse each line in /etc/passwd.
Using 'cut' or 'awk' to get the field (such as uid, gid...), compare with what
you get from running 'ls', output inconsistancy to a file.
For directory ownership, you might just compare it as a string. |

e.g, 100000, how to do that in bash or ksh using "for" loop? Is there anything
