And, I'm not sure what output from rm -f is intended to be captured in /tmp/text.txt either. With -f there won't be any file not found errors, and even if there were, they would be written to stderr instead of stdout.
It might be better if those two lines were replaced by the single line:
but I don't know if the author of this thread wants find and rm diagnostics to be on the screen or captured in the log file.

my %seen=();
foreach my $curr (@allwords) {
$seen{$curr} = 1;
}
@allwords = keys %seen;
my question is: what will @allwords now contain, or how would the entries in the @allwords array be different after this manipulation?
Thank... (3 Replies)

ps2ascii
PS2ASCII(1) Ghostscript Tools PS2ASCII(1)NAME
ps2ascii - Ghostscript translator from PostScript or PDF to ASCII
SYNOPSIS
ps2ascii [ input.ps [ output.txt ] ]
ps2ascii input.pdf [ output.txt ]
DESCRIPTION
ps2ascii uses gs(1) to extract ASCII text from PostScript(tm) or Adobe Portable Document Format (PDF) files. If no files are specified on
the command line, gs reads from standard input; but PDF input must come from an explicitly-named file, not standard input. If no output
file is specified, the ASCII text is written to standard output.
ps2ascii doesn't look at font encoding, and isn't very good at dealing with kerning, so for PostScript (but not currently PDF), you might
consider pstotext (see below).
FILES
Run "gs -h" to find the location of Ghostscript documentation on your system, from which you can get more details.
