I have a file that I need to use the substitute operator on to get
rid of spaces, and apostrophes and such. The only way I can think of
doing it is this:
1. Open the file and go through it one line at a time with the
diamond operator.
2. Make the substitutions on the $_ variable and save the changes in
an array.
3. Close the file, then re-open it and overwrite it with the array.
I was just wondering if there was an easier or better way of doing
this.
Why not slurp the file into a scalar?
Why need to slurp the file into a scalar?It consume your memory
quickly and maybe break the operation,given the file size is large.
Nobody said the file is large. You don't _need_ to slurp the file, but
doing so makes the subsequent processing more efficient (calling the
regex engine only once instead of one time per line).
