Hi,
I was wondering if there was a way to append something to filenames based on a wildcard. For example, if I have the following files in a directory:
blah1
blah2
blah3
blah4
blah5
I want to rename these all to:
blah1.txt
blah2.txt
blah3.txt
blah4.txt
blah5.txt
Is there a... (4 Replies)
HIya,
Having a dumb day whilst writing an archive process in Shell want to extract from the filename the date and archive into tar files based on this, I don't want to use mtime as it may not be the actual file date.
The files are

The files below are essentially “lookup files” used in a series of scripts that run through the look up files and grab the correct Group Name and File Type and then unless I have the file name specified will replace the variable with the corresponding group name when processing the files before...

Hi I'm very new to this script thing, so please be gentle.
I am trying to get a command - the mach2qtl command in the code below - to loop through a set of files.
Each command should take the same two .dat and .ped files, but the .mlinfo and .mlprob files with filenames including 'chrom1' ... (7 Replies)
I'm trying to search all .odt files in a directory for a string in the text of the file.
I've found a bash script that works, except that it can't handle whitespace in the filenames.

if ; then
echo "Usage: searchodt searchterm"
exit 1

Is firefox changing the filename of this hidden file for anyone else? I tried in firefox 3, 4, and 6. They all got changed when I tried when I downloaded the file. Firefox removed the leading dot that makes the file be hidden.

Hi all,
I want to generate output files in a loop, run the same command on the same input file 1000 times and output in files with a new name each time, maybe a number appended to it. The output will be different each time as I`m sampling randomly from the input file.
I want to do the... (3 Replies)
Hi,
I would like to write a loop to change the names of files in a directory. The files are called data1.txt through data1000.txt. I'd like to change their names to a1.txt through a1000.txt. How do I go about doing that? Thanks! (2 Replies)
Daily stupid question. I want to increment the file name everytime the script is run. So for example if the filename is manager.log and I run the script, I want the next sequence to be manager.log1. So to be clear I only want it to increment when the script is executed. So

WRJPGCOM(1) General Commands Manual 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/JFIF file, or the standard input if no file is named, and generates a new JPEG/JFIF file on standard 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 doesn't actually define what COM blocks
are for, they are widely used to hold user-supplied text strings. This lets you add annotations, titles, index terms, etc to your JPEG
files, and later retrieve them 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 as many of them as you like in one JPEG file.
wrjpgcom adds a COM block, containing text 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
Switch names may be abbreviated, and are not case sensitive.
-replace
Delete any existing COM blocks from the file.
-comment text
Supply text for new COM block on command line.
-cfile name
Read text for new COM block from named file.
If you have only one line of comment text to add, you can provide it on the command line with -comment. The comment text must be sur-
rounded with quotes so that it is treated as a single argument. Longer comments can be read from a text file.
If you give neither -comment nor -cfile, then wrjpgcom will read the comment text from standard input. (In this case an input image file
name MUST be supplied, so that the source JPEG file comes from somewhere else.) You can enter multiple lines, up to 64KB worth. Type an
end-of-file indicator (usually control-D) to terminate the comment text entry.
wrjpgcom will not add a COM block if the provided comment string is empty. Therefore -replace -comment "" can be used to delete all COM
blocks from a file.
EXAMPLES
Add a short comment to in.jpg, producing out.jpg:
wrjpgcom -c "View of my back yard" in.jpg > out.jpg
Attach a long comment previously stored in comment.txt:
wrjpgcom in.jpg < comment.txt > out.jpg
or equivalently
wrjpgcom -cfile comment.txt < in.jpg > out.jpg
