renaming files

[SaltyDuke]

hello.

i have a file called: hello.txt

and i would like to change it to HELLO.txt for reasons of National Security (well not relly ;-) )

so how do i go about doing this?? in other words, is there a "rename" command for filenames in Linux??

thanx

Ok, there's prettier ways to do this, but it'll work. Using bash (my shell of choice):

for i in *.txt; do mv "$i" `echo "$i" | tr [a-z] [A-Z]`; done

But that moves every hello.txt to HELLO.TXT. If the cap'd .TXT is a problem, next do:

for i in *.TXT; do mv "$i" `echo "$i" | tr [TXT] [txt]`; done

The extra " quotation marks will compensate for any spaces in your filenames.

I'm sure there's a more efficient way to do it, maybe using 'cut' and another variable, but this will get it done either way

Hi,

In 1 phase

for i in *.txt; do mv $i `echo $i | awk -F\. '{print toupper($1)}'`.txt; done

But if the job only concerns 1 file, "mv hello.txt HELLO.txt" is probable the shortest way ...

...uhhhh, how about "mv hello.txt HELLO.txt". Its a little simpler than writing a script to rename a file.

The mv command is used to both rename and move files/directories in Unix/Linux.
