Hi
I have a file all in uppercase that I wish to change to sentence case eg.

Anyone got any ideas?
Thanks

Hmmmm
Use tr to get to all lower case :
tr &quot;[:upper:]&quot; &quot;[:lower:]&quot; < capsfilename > lowfilename

Then, depending on your rules, use n/g/awk to do an upper
on the first character in each field - Can you post an example ?

Try something like this:

awk '{
for(i=1;i<NF;++i)
 printf &quot;%s%s &quot;,substr($i,1,1),tolower(substr($i,2))
printf &quot;%s%s\n&quot;,substr($NF,1,1),tolower(substr($NF,2))
}' /path/to/input >output

Hope This Help

Using awk...

echo SMITH | awk '{print substr($1,1,1) tolower(substr($1,2))}'

If you want to change all content to become sentence case. I wrote a script as follows:

#turn all to lower
y/ABCDEFGHIJKLMNOPQRSTUVWXYZ/abcdefghijklmnopqrstuvwxyz/

#change first letter of first line to upper
1 {
/^[a-z][^.]*.*$/ {
h
s/^\([a-z]\).*$/\1/
y/abcdefghijklmnopqrstuvwxyz/ABCDEFGHIJKLMNOPQRSTUVWXYZ/
G
s/^\(.*\)\n\([a-z]\)\(.*\)$/\1\3/
}
}

#turn any word after full stop to upper
:loop
/\. [a-z]/ {
h
s/^[^.]*\(\. [a-z]\).*$/\1/
y/abcdefghijklmnopqrstuvwxyz/ABCDEFGHIJKLMNOPQRSTUVWXYZ/
G
s/^\(\. [A-Z]\)\n\(.*\)\(\. [a-z]\)\(.*\)$/\2\1\4/
b loop
}

# if full stop appears in last position, change letter to upper in next line
/[a-z]\{2,\}\.$/ {
n
y/ABCDEFGHIJKLMNOPQRSTUVWXYZ/abcdefghijklmnopqrstuvwxyz/
/[a-z][^.]*.*$/ {
h
s/\([a-z]\)\(.*\)/\1/
y/abcdefghijklmnopqrstuvwxyz/ABCDEFGHIJKLMNOPQRSTUVWXYZ/
G
s/\(.*\)\n\([a-z]\)\(.*\)/\1\3/
b loop
}
}

#Should do this replacement in last part of the script
/^$/ {
n
y/ABCDEFGHIJKLMNOPQRSTUVWXYZ/abcdefghijklmnopqrstuvwxyz/
/^[a-z][^.]*.*$/ {
h
s/^\([a-z]\).*$/\1/
y/abcdefghijklmnopqrstuvwxyz/ABCDEFGHIJKLMNOPQRSTUVWXYZ/
G
s/^\(.*\)\n\([a-z]\)\(.*\)$/\1\3/
b loop
}
}


Hope it may be useful for you. If it can't handle any cases pls. let me know.
