E.g.,

Code:
Before After
--------------
emily-yellow.extension emily-yellow.anotherword.extension/possiblysomethingelse
Emily-yellow.extension Emily-yellow.anotherword.extension/possiblysomethingelse
emily-Yellow.extension emily-Yellow.anotherword.extension/possiblysomethingelse
Emily-Yellow.extension Emily-Yellow.anotherword.extension/possiblysomethingelse

Basically I want to preserve the case in the words
At least:
-the first letter in the entire keyword
-first letter after the -
-first letter of the extension


right now i'm writing the second keyword in lowercase in the see command but i want to keep it as the same case as the original. sometimes occurrences are the beginning of a sentence, some occurrences are not. if it is, i want to also be capitalised upon replacing

---------- Post updated at 12:23 AM ---------- Previous update was at 12:17 AM ----------

actually i have another problem

I'm doing something like

Code:
UPDATE $optionstable SET option_value = replace(option_value,"$BEFORE","$AFTER") WHERE wp_otpions.option_name = 'blogname';


but the problem is that this only replaces the specific case of "$BEFORE"

how can i make it case insensitive?
thanks

Okay, so this is what I'm trying now


blognamebefore = (i put in a sql command to grab the blog name)
This can be anything like "afdsdsfasdf BEFORE fafdsadffdsds"

then I'm trying to run a sed command that does a replace of the BEFORE keyword to the AFTER keyword

sed 's!${BEFORE}!${AFTER}!gI'


I want to preserve the case of the BEFORE word, at least the first letter would be good

how can I do this?



when I run the sed command, it changes the keyword into all lowercase letters

and I don't want to do this especially in the title

I think I managed something for now
I googled about how to use sed to capitalise the first letter of a word
then use that as my new keyword

sethead

sethead(1)						      General Commands Manual							sethead(1)

Name
       sethead - Set FITS or IRAF header keyword values

Synopsis
       sethead [-dknv][r letter] <FITS or IRAF file> kw1=val1 kw2=val2 ... kwn=valuen

Description
       Set parameters in the header of a FITS or IRAF image.  If the keywords do not already exist, they are added at the end of the header.  Val-
       ues are assumed to be numeric if they contain no alphabetic characters and right-aligned.  Otherwise they are left-aligned after the equals
       sign,  and padded by spaces to a minimum of 8 characters.  To set keywords in a list of files, substitute @<listfile> for the file names on
       the command line.  To set a lot of keywords, put them, one per line, in a file and substitute @<keylistfile> on the command line.  If two @
       commands  are  present,	the  program  will figure out which contains file names and which contains keywords.  Lines in a keyword list file
       which do not contain an = are ignored.

Options
       -h     Write HISTORY line into output header with sethead version, current date and time, and names of keywords set.

       -k     Write SETHEAD keyword into output header with sethead version, current date and time, and names of keywords set.	If a SETHEAD  key-
	      word already exists, move the old value to a HISTORY line before writing the new value

       -n     Write a new file with an added "e" before the extension.

       -r letter
	      Rename  existing keywords whose values are being reset by prepending the character "letter".  Drop the last character if the changed
	      keyword is already 8 characters long.

       -v     Print confirmations of each parameter setting
