I'm not sure on using backquotes is wrong per se.
$(command) are both `command` are both currently valid syntax and in standards.
Exception being, that actually backquotes should work on even the oldest shells (and new ones), while other form might not.
If i'm not mistaken backquotes are still the lowest common denominator for command substitution if you wish your scripts to work anywhere without touching
But today it's hard to find such shells as defaults or even existing on operating systems.
So i tend to write scripts using $(command) method, as well as promote such way.

I'm always concerned I might be abusing backticks within my scripts. A current script I'm writing has this for example:
stripscriptname=`echo $scriptname | sed 's/\(.*\)\..*/\1/'`
stripsearch=`echo $searchpattern | tr -d ' ,/'`
Both of these variables are set inside the script (in fact,... (2 Replies)

Here's an example
Find /mydir -name *.conf |xargs rm
Vs
Rm 'find /mydir -name *.conf'
Is there a performance hit? I know they do the same thing but which is... (1 Reply)
