AWK - changing first char from small to upper
I need to write script in AWK, changing first char from a line from lower to upper.
I found function toupper etc. but have no idea how to sent only first char from every line instead of the whole line. Anyone has any idea?

Hi bbqtoss,

What about a space as first char, or a paretheses?

Regards,
Birei

Just extract the first character from the line using substr() and after converting to uppercase, just concatenate with the remaining part.

An example might help:

Code:
awk '{ print toupper( substr( $0, 1, 1 ) ) substr( $0, 2 ); }' input-file >output-file

converts the first character of every record to uppercase (if it is lower) and then prints the line.

try this:
Code:
awk -vFS="" -vOFS="" '{$1=toupper($1);print $0}' filename

I believe it will not satisfy his requirement:
the proof for it's failure:
Code:
echo hiahihi|awk '{FS="";print $1}'
hiahihi
echo hiahihi|awk '{FS="";OFS="";print $1}'
hiahihi

so, even if you apply
Code:
toupper()

for $1 it will convert whole string to uppercase, but his requirement is to make the first letter aslone uppercase.
