LOGNAME
Code:
LOGNAME = 'id | awk '{begpos = index($0,"(") Endpos = index($
0,")") print substr($0,begpos+1,endpos-begpos-1) }'; export LOGNAME

-bash: syntax error near unexpected token `('

I am getting this error

The script is too difficult to follow if we assume a Posix Shell.

What Shell are you using?
What Operating System and version are you running?

What answer do you need in the environment variable $LOGNAME ?

I suppose that actually you want something like this:

Code:
LOGNAME="$(
  id | 
    awk '{ 
      begpos = index($0, "("); endpos = index($0,")") 
      print substr($0, begpos+1, endpos-begpos-1) 
      }'
    )" 
    
export LOGNAME

And you may try this command instead:

Code:
id -un

On Solaris use /usr/xpg4/bin/id.

Hmm I wondered about the space either side of the first equal sign. Is this csh or something else?

I suppose it's just wrong, the OP seems to be using bash, given the error message.

Actually, yes, those spaces could be a csh artifact Smilie

Most versions of unix "login" set $LOGNAME for you.

I wonder what Operating System this is.


If it wasn't set (and we have a normal Shell) I'd be tempted to use:
Code:
LOGNAME=`who am i|awk '{print $1}'`
or
LOGNAME=$(who am i|awk '{print $1}')


OMG. -bash does indeed appear in post #1. Looks like the spaces are a typo. Also "id -un" is cool.
