00123
14567
what i want is a command to check if the number is starting from 0 and then delete the 0 without doing anything else!!!!
any help wud b appreciated!!!!!!!!:( (4 Replies)

Hello,

I have a 12 column csv file. I wish to delete the entire line if column 7 = hello and column 12 = goodbye. I have tried everything that I can find in all of my ref books.

Any ideas?

yuv2lav
yuv2lav(1) MJPEG tools manual yuv2lav(1)NAME
yuv2lav - encodes lavtool's raw YUV frame streams into MJPEG files
SYNOPSIS
yuv2lav [-f a|A|q|m] [-q num] [-b num] [-I num] [-m num] [-v num] [-w file] -o output-file
DESCRIPTION
yuv2lav is a simple MJPEG encoder for raw YUV frame streams as they are emitted by lav2yuv(1) or lavpipe(1), for example. It reads its
input from stdin and is capable of writing AVI and Quicktime.
OPTIONS
The command line options allow to specify the output file name, JPEG encoding quality and the amount of memory that will be allocated for
JPEG compressed data.
-o output-file
This (compulsorary) option sets the name of the file that yuv2lav will write its output to. If the output file contains a % (e.g.
file%02d.avi), the output will be written to multiple files in case this is necessary (file00.avi, file01.avi and so on).
-f a|A|q
This sets the output file format, which has to be one of
a - for AVI file output,
A - for AVI with reversed fields,
q - for Quicktime output or
AVI with reversed field of course only makes sense if yuv2lav's feed is an interlaced video source and should only be needed if you
experience frame reversal problems in your output. If you don't use that option yuv2lav will set the output format to AVI if the
last 3 char are avi, or to Quicktime if you use mov. If you use the -f option it overides the setting in the filename
-q num This option specifies the JPEG encoding quality as passed through to libjpeg. The default value is 80, num must lie within 24...100
inclusive (think of it as percentage values, although with a lossy compression algorithm like JPEG, keeping 100% of the original
quality is of course not really possible).
-b num This option specifies the size of the buffer (in kBytes) that yuv2lav allocates in order to store the compressed JPEG data in it.
The default value (256k) is perfectly enough for 100% quality full sized PAL/NTSC, but if you want to compress Super-Mega-HDTV or if
you are low on memory, you can use this option to suit your needs.
-m num This is the maximum size (in MB) per file. Normally this depends on the output file type.
-I num Force a specific interlacing type. 0 means no interlacing, 1 means top-field-first, 2 means bottom-field-first.
-w file
This is the WAV file containing audio data to be combined with the video stream into the output file.
-v num Verbosity level. 0 means only print error messages, 2 prints full debug output.
-? Display a synopsis of the command syntax.
EXAMPLES
lav2yuv movie.avi | yuv2lav -fq -q 30 lowbitrate.qt
would recompress movie.avi as a low bit rate Quicktime file.
lavpipe input.pli | yuv2lav -q80 output.avi
would save the movie assembled by lavpipe as a single AVI file.
