I have a bunch of files like "a.HTM, a.HTM" etc. I want to rename
them "a.html, b.html".

So, I tried cp *.HTM *.html. I get the following message:

cp: Target 201_01.html must be a directory
Usage: cp [-i] [-p] f1 f2
cp [-i] [-p] f1 ... fn d1
cp [-i] [-p] [-r] d1 d2

(201_01.html is a file in the directory).

So, what do I have to do to rename these files?

Thanks,

Ray

There is also something called mmv; no doubt a search engine can find
it.

I use a routine called mved ( there is also one called cped).
The useage is

mved =.HTM =.HTML

Unfortunately I can not recall where it came from. Can anyone help
and give the source.

Cheers, Brian.

Using sh, you could do something like

for i in *.HTM
do
cp $i `basename $i .HTM`.html
done

See basename(1) and cp(1) [and possibly mv(1)] for details.
As you wanted to rename files, you should rather use "mv"
instead of "cp"...

This command should work

foreach file (*.htm)
mv $file $file:r.html
end

This is a classic textbook example of the csh - foreach command.
However, some text was left out of the first line. The code in
parentheses (sp?) should generate a word list for the variable file
hence the use of backquotes (`). So the first line with the rest of the
shell should look like this:

foreach file (`ls *.htm`)
mv $file $file:r.html
end

This can also be run from the command line:

% foreach file (`ls *.htm`)
? mv $file $file:r.html
? end

This general rename script that I just wrote should do it too:

rename *.HTM =.html

Bo Siltberg

#!/bin/sh -fh
#
# Rename parts of file names.
#
# Created: 97-10-25 BY Bo Siltberg REV. A
#
# Format: rename inputfiles outputfile
#

pgmname=`basename $0`

usage()
{
more << END_HELP

Rename a number of files.

Format: $pgmname infiles... outfile

The file names are split into units. An "=" in the output unit is
replaced with the corresponding name from the input unit.

Example:
$pgmname mfm.code =R6A.= -> mfmR6A.code
$pgmname mfm.code bus.= -> bus.code
$pgmname mfm.code ==.= -> mfmmfm.code
$pgmname mfm.code.gz bus.= -> bus.code.gz
$pgmname mfm.code.gz =.object.= -> mfm.object.gz

However, the basic idea with this command is to rename a number of
files:
$pgmname mfm.* bus.= -> All files starting with 'mfm.' are
given the prefix 'bus.' instead.

(t)csh:

foreach i (*.HTM)
mv $i ${i:r}.html
end

bash:

for i in *.HTM; do
mv $i ${i%HTM}.html
done

ksh: no idea

I'd also have suggested

ls *.HTM | xargs -i mv {} `basename {} HTM`html

but that is broken...

I've done the "trouble" already, so no trouble for you.
And the result is a simple command syntax of a general purpose
renaming script.

I cannot understand why one would like to write commands like
"mv $file <={~~ $file *.HTM}.html" all the time. Unless one are
an *ed UNIX hacker, it is time consuming to find out
this syntax. But UNIX is maybe not meant for "normal" users?
