Re: How to use a variable in tr///

[chanio]

Two points to remember:

• 1. I shouldn't trust so easily in what others say.
• 2. I should frequently practice with my monitor some oneliners with the examples that I learn...

Why? This is what I have just tryed...

perl -e"$old='abc';$old = tr/a/z/g;print \"$old \n\";"
Bareword found where operator expected at -e line 1, near "tr/a/z/g"
syntax error at -e line 1, near "tr/a/z/g"
Execution of -e aborted due to compilation errors.

There is no tr///g since every replacement is done on all the characters. So the /g would always be unnecesary. Just try it!
