error in a variable

mierdatuti · 04-21-2015, 04:10 AM

Hi,
Someone could help me with these sentence?

Code:

per=`print "scale=2; $sum/$count" | bc`

It says me:

Code:

(standard_in) 1: parse error

Why?

pan64 · 04-21-2015, 04:11 AM

what will
print "scale=2; $sum/$count"
respond? (without backticks and pipe and bc)

OP: Do you really have a command named 'print'.

Code:

which print

would show one if exists.

If this is a script of some type, perhaps you can post the rest of it, because where are $sum and $count defined?

The use of print suggests that the OP has a script written for ksh, the Korn Shell.
The syntax error arises when it is run in another shell such as bash.

I wonder if they intended to use print or perhaps they chose it due to C programming and not realizing that it's not the same in the shell. @OP if your intention was to output the result of that computation, a better choice here would be echo. What would also help would be to overview what you're doing, or trying to accomplish, what script type you're using, and so forth.
