Change lower case

Nobody's Hero — Tue, 22 Mar 2005 10:20:20 GMT

Is there a script or utility that allows me to change an ascii file from lower case to upper case?

The entire file is lower case and I want it to be upper case.

Robert,

Use

cat file | tr 'a-z' 'A-Z'

tr -s '[:upper:]' '[:lower:]'

Do a man on tr.

Yet another different way of doing it:

# awk '{print toupper($0)}' filename > filename.new

Pete,
I believe your [:upper] and [:lower] are the wrong way round ;-)

Hey Robert,
Thanks for posting this question. I've just learned the easy way of doing this. I've not needed to do an entire file before, just certain sections within a file. I've done this manually by putting my cursor over the first letter to change to uppercase (or this works also for lowercase) and holding the shift key down and pressing the ~ (tilde) key. Holding these keys down changes the case from lower to upper or upper to lower (depending on the current case) until I release the keys.

Again, thanks for posting your question.

Hey Robert,
I couldn't get this to work:
# cat file | tr 'a-z' 'A-Z'

but I could get this to work:
# cat file | tr -s '[:lower:]' '[:upper:]'

Again, thanks.

Hey Robert,
Sorry, forgot the complete syntax for converting a file from lowercase to uppercase ...

# cat | tr -s '[:lower:]' '[:upper:]' >

If you want to do this in C, here is it:

--- File toupper.c ----
#include
#include
int main ()
{
for (;!feof(stdin);)
fputc (toupper(fgetc (stdin)), stdout);
return 0;
}
---- End ---
Save above file in toupper.c and compile.
# cc toupper.c -o toupper

Execute it as:
# cat you_file | toupper
