I strongly advise that you hide these filenames from Shell and avoid trying to put them into Shell environment variables. Try to work with external commands only.
Use unix "find" to generate a list of filenames into a file.
Then create a "sed" file containing your "sed" commands. Because Shell will not see them we only need to escape characters where "sed" requires it (which it will with some of these filenames!).
Run with the outline syntax:
Throughout this exercise we must avoid Shell seeing the filenames.
Hi All,

Hi All,
I need to rename the multiple file names.
I need to rename for example as follows
bas100e1_jun05 to FLAT1
bas100e2_jun05 to FLAT2
bas100e18_jun05 to FLAT18
Please not that I can cut_jun05 from the filename. Madhan had helped with a similar kind of script. But this is a new... (4 Replies)
Is it possible in VI to do a global change but take the search patterns and the replacement patterns from an external file ?

Hi :)
Is there any command I could use to rename a bunch of files resident of the same location to their original name plus a fixed text string of my own?
Example:
File1
File2
File3
Output:
File1.txt
File2.txt
File3.txt
This is easy using a "for" loop but what I want is a one-line... (5 Replies)
Hey folks
My problem is simple. For my first stash of movies, I used a naming convention of YEAR_MOVIE_NAME__QUALITY/ for each movie folder. For example, if I had a 1080p print of Minority Report, it would be 2002_Minority_Report__1080p/.
The 2nd time around, I changed the naming convention... (4 Replies)

avisplit
avisplit(1) General Commands Manual avisplit(1)NAME
avisplit - split AVI-files into chunks of a maximum size
SYNOPSIS
avisplit [ -i file -o base [ -s size ] [ -H num ] [ -t s1-s2[,s3-s4,..] -c -m -b num -f commentfile ] ] [ -v ]
COPYRIGHT
avisplit is Copyright (C) by Thomas Oestreich.
DESCRIPTION
avisplit splits a single AVI-file into chunks of size size.
Each of the created chunks will be an independent file, i.e. it can be played without needing any other of the chunk.
OPTIONS -i file
Specify the filename of the file to split into chunks.
-o base
Specify the base of the output filename(s) avisplit will then split to base-%04d.avi
-s size
Use this option to specify the maximum size (in units of MB) of the chunks avisplit should create. 0 means dechunk, create as many
files as possible.
-H num Create only the first num chunks then exit.
-t s1-s2[,s3-s4,..]
Split the input file based on time/framecode (hh:mm:ss.ms)
-c Together with -t. Merge all segments into one AVI-File again instead generating seperate files.
-m Together with -t. Force split at upper bondary instead of lower border.
-b num Specify if avisplit should write an VBR mp3 header into the AVI file. Default is 1 because it does not hurt. num is either 1 or 0.
-f commentfile
Read AVI tombstone data for header comments from commentfile. See /docs/avi_comments.txt for a sample.
-v Print only version information and exit.
EXAMPLES
The command
avisplit -s 700 -i my_file.avi
will split the file my_file.avi into chunks which's maximum size will not exceed 700 MB, i.e. they will fit onto a CD, each. The created
chunks will be named my_file.avi-0000, my_file.avi-0001, etc.
avisplit -i my_file.avi -c -o out.avi -t 00:10:00-00:11:00,00:13:00-00:14:00
will grab Minutes 10 to 11 and 13 to 14 from my_file.avi and merge it into out.avi
BAD SYNCH
When you split a file with avisplit and the A/V sync for the first file is OK but the sync on all successive files is bad then have a look
at the output of tcprobe(1) (shortend).
| V: 25.000 fps, codec=dvsd, frames=250, width=720, height=576
| A: 48000 Hz, format=0x01, bits=16, channels=2, bitrate=1536 kbps,
| 10 chunks, 1920000 bytes
You'll see the AVI file has only 10 Audio chunks but 250 video chunks. That means one audio chunk spans several video frames. avisplit can
not cut a chunk in half, it only handles complete chunks. If you do, say, avisplit -s 20, it is possible that the first file will have 6
audio chunks and the second one only 4 meaning there is too much audio in the first AVI file.
The solution is to remux the AVI file with
transcode -i in.avi -P1 -N 0x1 -y raw -o out.avi
(of course -N 0x1 is not correct for all AVI files). Now look at tcprobe again
| V: 25.000 fps, codec=dvsd, frames=250, width=720, height=576
| A: 48000 Hz, format=0x01, bits=16, channels=2, bitrate=1536 kbps,
| 250 chunks, 1920000 bytes
The data in this file is exactly the same (its bit-identical) as it was in in.avi; the AVI file was just written in a different way, we do
now have 250 audio chunks which makes splitting much easier and more accurate for avisplit.
