Thank you greet_sed and dry!


Great postings. I finally understood your answers! It's working Smilie

I installed the command rename via homebrew. This is a great help too.

Yes, I should move to bash. But I am so accustomed to commands like:

Code:
cp file_w30.tex !#:1:s/_w30/_w31/

would this be possible in bash too?

Thank you again

Hi,

Following one works in bash from terminal through bash history ( Not from the script ) :
Code:
cp file_w30.tex !#:1:s/_w30/_w31/

!# - Refers to current command line typed so far.
1 - Refers to word 1 ( it starts from 0 - cp , 1 - file_w30.tex )
s/// - substitute _w30 to _w31

you can try like this from bash script :
Code:
cp file_w{30,32}.tex

Code:
 
READLINE
       This is the library that handles reading input when using  an  interac-
       tive shell, unless the --noediting option is given at shell invocation.
       Line editing is also used when using the -e option to the read builtin.
       By default, the line editing commands are similar to those of Emacs.  A
       vi-style line editing interface is also available.  Line editing can be
       enabled  at  any  time  using  the -o emacs or -o vi options to the set
       builtin (see SHELL BUILTIN COMMANDS below).  To turn off  line  editing
       after  the  shell  is running, use the +o emacs or +o vi options to the
       set builtin.
...
      yank-nth-arg (M-C-y)
              Insert  the  first argument to the previous command (usually the
              second word on the previous line) at point.  With an argument n,
              insert  the nth word from the previous command (the words in the
              previous command  begin  with  word  0).   A  negative  argument
              inserts the nth word from the end of the previous command.  Once
              the argument n is computed, the argument is extracted as if  the
              "!n" history expansion had been specified.

Excerpt from man bash, q.v., describing one (small) part of the emacs editing mode for previously entered commands in the history. This is a very general scheme for editing commands. The advantage is that it uses emacs-like commands, so once you know one, the other is similar. Personally, I use the vi mode.

Best wishes ... cheers, drl

Thank you!

Code:
cp file_w{30,32}.tex

That's really amazing! Very elegant! I will definately switch to Bourne shell. Opening a new thread, could somebody help me to move my .tcshrc profile to .bashrc ? Or would this be to childish for this professional forum?

Thanks again

There's nothing like childish questions. But - you can help avoid even the impression by showing a correct and professional approach: formulate your request carefully, show your own attempts and where and how they fail (including details, e.g. error messages), and how you started curing the failures (e.g. applying topics from man pages).

And, yes, START a NEW thread - don't continue this old and solved one.
