Cp and create files as {,.bak}
Hello Guys,
As the perefect lazy administrator was wondering if is possible to create several files from one instance as the quick tip of doing this using "cp" ;
$ cp demofile demofile.bak
or
$ cp demofile{,.bak}
$ls
demofile.bak
Something like the following e.g. using "touch" ...
v1ct0r$ touch test{1..8}.txt
v1ct0r$ ls
test1.txt test2.txt test3.txt test4.txt test5.txt test6.txt test7.txt test8.txt
...my try;
v1ct0r$ touch uno
v1ct0r$ cp uno{,3..4}
v1ct0r$ ls
uno uno3..4
...my desire output:
uno uno3 uno4
Thanks!

RENAME(1) Perl Programmers Reference Guide RENAME(1)
NAME
rename - renames multiple files
SYNOPSIS
rename [ -v ] [ -n ] [ -f ] perlexpr [ files ]
DESCRIPTION
"rename" renames the filenames supplied according to the rule specified as the first argument. The perlexpr argument is a Perl expression
which is expected to modify the $_ string in Perl for at least some of the filenames specified. If a given filename is not modified by the
expression, it will not be renamed. If no filenames are given on the command line, filenames will be read via standard input.
For example, to rename all files matching "*.bak" to strip the extension, you might say
rename 's/.bak$//' *.bak
To translate uppercase names to lower, you'd use
rename 'y/A-Z/a-z/' *
OPTIONS
-v, --verbose
Verbose: print names of files successfully renamed.
-n, --no-act
No Action: show what files would have been renamed.
-f, --force
Force: overwrite existing files.
ENVIRONMENT
No environment variables are used.
AUTHOR
Larry Wall
SEE ALSO
mv(1), perl(1)
DIAGNOSTICS
If you give an invalid Perl expression you'll get a syntax error.
BUGS
The original "rename" did not check for the existence of target filenames, so had to be used with care. I hope I've fixed that (Robin
Barker).
