Instead of a file you can use a pipeline or a here-document as well, i.e.:
The interesting part of the code is this:
Setting the IFS variable to some character means the input is split up into "words" at exactly this character. The variables ("var1", "var2", ...) are assigned these words one after the other. If your input would look like this:
I have a script which selects two 'sets' of system LVM device files from a tabular file 'mapfile' using awk :
LIVELV=`awk '{print($1)}' mapfile`
BCVLV=`awk '{print($3)}' mapfile`
I wanted to pass these 'sets' into an LVM command 'loop' along the lines of :
lvmerge $BCVLV $LIVELV

Hi,
I have two variables like below which will always be of the same size

I need to use a for/while loop that will have both the variables available. I cannot use an array here and will probably might iterate through the variable as echo $a | tr ':' '\n' and thus iterate... (5 Replies)

Subtitles(3pm) User Contributed Perl Documentation Subtitles(3pm)NAME
Subtitles - handle video subtitles in various text formats
DESCRIPTION
Video files (avi mpeg etc) are sometimes accompanied with subtitles, which are currently very popular as text files. "Subtitles" provides
means for simple loading, re-timing, and storing these subtitle files. A command-line tool subs for the same purpose and using "Subtitles"
interface is included in the distribution.
The module supports "srt", "sub", "smi", and "mdvd" subtitle formats.
Time values are floats, in seconds with millisecond precision.
SYNOPSIS
use Subtitles;
my $sub = Subtitles->new();
open F, 'Ichi The Killer.sub' or die "Cannot read:$!";
die "Cannot load:$@
" unless $sub-> load(*F);
close F;
# back two minutes
$sub-> shift( $sub-> parse_time('-02:00'));
# re-frame from 25 fps
$sub-> scale( 23.976 / 25 );
# or both
$sub-> transform( -120, 0.96);
$sub-> transform( -120, 0.96, 0, $sub-> length - 60);
# split in 2
my ( $part1, $part2) = $sub-> split( $self-> length / 2);
# join back with 5-second gap
$part1-> join( $part2, 5);
# save
open F, "> out.sub" or die "Cannot write:$!
";
$part1-> save( *F);
close F;
# report
print "sub is ", time2str( $sub-> length);
API
Package methods
codecs
Returns array of installed codecs.
hms2time HOURS, MINUTES, SECONDS, MILLISECONDS
Combines four parameters into float time in seconds.
time2hms TIME
Splits time into four integers, - hours, minutes, seconds, and milliseconds. If time is less than zero, zero times are returned.
time2shms
Splits time into five integers, - time sign, hours, minutes, seconds, and milliseconds.
time2str TIME
Converts time to a human-readable string.
Object methods
clear
Removes all content
codec [ STRING ]
If STRING is not defined, returns currently associated codec. Otherwise, sets the new codec in association. The STRING is the codec's
package name, such as "Subtitles::Codec::srt".
dup [ CLEAR ]
Duplicates object instance in deep-copy fashion. If CLEAR flag is set, timeframes are not copied.
join GUEST, GAP
Adds content of object GUEST at the end of the list of subtitles with GAP in seconds.
length
Returns length of subtitle span.
load FH [ CODEC ]
Reads subtitle content into object. If successful, returns 1; otherwise undef is returned and $@ contains the error.
By default, tries to deduce which codec to use; to point the selection explicitly CODEC string is to be used.
lines
Returns number of subtitle cues.
new Creates a new instance. To force a particular codec, supply "codec" string here.
parse_time STRING
Parses STRING which is either a "[[HH:]MM:]SS[,MSEC]" string or string in a format specific to a codec, for example, number of a frame.
rate FPS
Forces a particluar frame-per-second rate, if a codec can make use of it.
save FH
Writes content of instance into FH file handle, using the associated codec.
scale A
Changes time-scale. If A is 2, the subtitles go off 2 times slower, if 0.5 - two times faster, etc.
shift B
Shifts timings by B seconds. B can be negative.
split TIME
Splits the content of the instance between two newly created instances of the same class, by TIME, and returns these. The both
resulting subtitles begin at time 0.
transform A, B [FROM, TO]
Applies linear transformation to the time-scale, such as "u = At + B" where "t" is the original time and "u" is the result. If FROM and
TO brackets are set, the changes are applied only to the lines in the timeframe between these.
BUGS
This is alpha code, more a proof-of-concept rather that anything else, so most surely bugs are lurking.
Anyway: not all subtitle types are recognized. The modules doesn't handle multi-language subtitles.
