Solaris

Hi

I have set PS1 in my profile as -
PS1='${LOGNAME}@${PWD}>' ; export PS1

it works fine if I am in bash/ksh shell, but as soon as i switch to bourn shell (sh) then it shows "${LOGNAME}@${PWD}>" as prompt.

It is also not working in csh.

Please help.

I believe ${LOGNAME} ${PWD} are special ,,metacharacters'' that are interpreted by shell. bash, ksh are modern shells with a lot of capabilities, sh and csh are more simple shells that don't have all that fancy stuff.

shell is sort of programming language, in .vbs (forgive me this example here) a variable is simply wirrten like var, in perl/shell you need to write $var, what you spotted is simply one of differences between csh, sh, ksh, bash.

but Togr, I believe LOGNAME and PWD are shell variables and even if you type echo ${LOGNAME} or ${PWD} in bourne shell (sh) , it will give u the result.
sorry if I am wrong.

Is it possible to have consistent prompt irrespective of shell in use.

Thanks for ur reply togr.

I never worried about that much, to be honest.
I'd not be surprised if sh simply did not interpret these character the way bash does.

I tried on a FBSD (which has real sh, not linked bash) and managed something like this:

Code:

${LOGNAME} echo $PS1
${LOGNAME}
${LOGNAME} bash
[root@fbsd ~]# echo $PS1
[\u@\h \w]\$
[root@fbsd ~]# exit

this got interpreted:

Code:

${LOGNAME} PS1="${PWD}"
/root

but was assigned statically:

Code:

/root cd ..
/root

is there any particular reason or this is just an excersise for you?
