tr command
Hi.
This is my first post,
I am trying to change certain sections of a file from UPPERCASE to lowercase. For this I am using the tr command. The thing is it is changing all of the text in the file to lowercase. My question is "can you use pattern matching or something in conjunction with tr to selectively change text?"
Eg: my code is
line_x (P) { ....
line_y (Q) { ...........
line_z(P Q) {..............
I only want to make whatever is in line_y to lowercase.
(there are multiple instances of line y)
Currently I am doing something like this:
tr "*(line_y ([A-Z]) {)" "*(line_y ([a-z]) {)" < file.orig > file.mod
but this is still just making all text lower case.
Any help or input would be greatly appreciated.
Kind Regards,
Colum.

towlower(3) Library Functions Manual towlower(3)
NAME
towlower, towupper - Convert uppercase and lowercase wide characters
LIBRARY
Standard C Library (libc)
SYNOPSIS
#include <wctype.h>
wint_t towlower ( wint_t wc);
wint_t towupper ( wint_t wc);
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
towlower(), towupper(): XSH5.0
Refer to the standards(5) reference page for more information about industry standards and associated tags.
PARAMETERS
Specifies the wide character to convert.
DESCRIPTION
The towlower() function converts the uppercase wide character specified by the wc parameter into the corresponding lowercase wide charac-
ter. The towupper() function converts the lowercase wide character specified by the wc parameter into the corresponding uppercase wide
character. The behavior of the towlower() and towupper() functions are affected by the LC_CTYPE category of the program's locale.
[Tru64 UNIX] In a locale where case conversion information is not defined, these functions determine the case of characters according to
the rules of the C locale.
RETURN VALUES
In the towlower() function, if the wc parameter contains an uppercase wide character that has a corresponding lowercase wide character,
that wide character is returned. Otherwise, the wc parameter is returned unchanged.
In the towupper() function, if the wc parameter contains a lowercase wide character that has a corresponding uppercase wide character, that
wide character is returned. Otherwise, the wc parameter is returned unchanged.
