Hi everyone! Here's my first thread...
I have to recognize if a TIFF image is corrupted or not.
I've always usedfile -b to identify file type, but I've experienced that sometimes it returns "TIFF image data, little endian" even if the image is truncated or something.
Do you know another trick... (6 Replies)

Hi,
I have a perl script which is a part of a shell script which read lines from a flat file(which is generated as part of a script after a series of bteq/fexp) and assigns a value for each object in the file based on the type of file name. (i.e extensions like .bteq/.ctl/.ksh etc)
For example,... (1 Reply)

wrjpgcom(1) User Commands wrjpgcom(1)NAME
wrjpgcom - insert text comments into a JPEG file
SYNOPSIS
wrjpgcom [-replace] [-comment text] [-cfile name] [filename]
DESCRIPTION
wrjpgcom reads the named JPEG or JFIF file, or the standard input if no file is named, and generates a new JPEG or JFIF file on the stan-
dard output. A comment block is added to the file.
The JPEG standard allows "comment" (COM) blocks to occur within a JPEG file. Although the standard does not actually define the intended
function of COM blocks, they are widely used to hold user-supplied text strings. This enables you to add annotations, titles, index terms,
and so on to your JPEG files, and later retrieve the COM blocks as text. COM blocks do not interfere with the image stored in the JPEG
file. The maximum size of a COM block is 64K, but you can have many COM blocks in one JPEG file.
wrjpgcom adds a COM block, containing text that you provide, to a JPEG file. Ordinarily, the COM block is added after any existing COM
blocks, but you can delete the old COM blocks if you wish.
OPTIONS
The following options are supported:
-cfile name Read the text for a new COM block from the named file.
-comment text Supply the text for a new COM block on the command line.
-replace Delete any existing COM blocks from the file.
OPERANDS
The following operands are supported:
filename The name of the JPEG file to which you want to add text comments.
EXTENDED DESCRIPTION
To add only one line of comment text, use the -comment option to provide the text on the command line. Specify the comment text within
quotes, so that the text is treated as a single argument. Longer comments can be read from a text file.
If you specify neither the -comment nor the -cfile option, wrjpgcom reads the comment text from standard input. In such cases, you must
supply an input image filename. You can enter multiple lines, up to 64KB. Type an end-of-file indicator, usually Ctrl-D, to terminate the
comment text entry.
wrjpgcom does not add a COM block if the provided comment string is empty. Therefore, you can use -replace -comment "" to delete all COM
blocks from a file.
EXAMPLES
Example 1: Adding a Short Comment to in.jpg to Produce out.jpg
example% wrjpgcom -c "View of my back yard" in.jpg > out.jpg
Example 2: Attaching a Long Comment Previously Stored in comment.txt
example% wrjpgcom in.jpg < comment.txt > out.jpg
or
example% wrjpgcom -cfile comment.txt < in.jpg > out.jpg
In this example, 1000 is a number that is larger than the number of rows in the source file.
