Shell Programming and Scripting

I have a script that has quite a lot of these types of entries:

Code:

hello=$(who am i)
good=$(blahblah)

what i want to do is replace the

Code:

$(

and the

Code:

)

with

Code:

``

so that they look like this:

Code:

hello=`who am i`
good=`blahblah`

I tried this:

Code:

:%s~=$(&&)$~=`&&`$~g

but of course it failed miserably. can anyone help me fix this?

im having to do this because the script needs to run on SunOS but solaris doesnt seem to like the

Code:

$()

after vi .. you have to press 'Ecs' then ':' then
try

Code:

%s/$(/`/g

and

Code:

%s/)/`/g

Not sure why it is not running at your end.
But i have Solaris and i tried to run

Code:

hello=$(who am i)
good=$(uname -a)
echo $hello
echo $good

output

Code:

[Makarand] # ./sky.sh
mak pts/4 May 13 13:29 (10.214.28.125)
SunOS Makarand 5.8 Generic_117350-61 sun4u sparc SUNW,Sun-Fire-V440

i actually tried this already. unfortunately, this script actually has several variations of $(......)

i need to be able to only make the changes to back ticks if and only if the line contains:

Code:

=$(

and ends with a

Code:

)

SunOS could care less about $(cmd) versus `cmd`. However, /bin/sh on Solaris systems is an old Bourne shell that doesn't recognize the $(cmd) form of command substitution. If you can change your script to use /usr/xpg4/bin/sh, /usr/xpg6/bin/sh, /bin/ksh, or /bin/bash instead of /bin/sh as its interpreter, you won't need to change to back ticks.

If you can't, use the following command in vi to change the command substitutions following an equals sign that end at the end of a line in the file you're editing:

Code:

:g/=\$(\(.*\))$/s//=`\1`/
