Input:
hello
world
monkey
Output should be:
Hello
World
Monkey
How can it be done with perl,sed,awk or bash?
awk -F "" '{$1=toupper($1)}1' OFS= file
Wow, cool...would you please explain a little bit for this code?
sed 's/^./\u&/' file
Hi,
$ perl -ne 'print ucfirst' infile
Regards,
Birei
perl -ne 'print ucfirst($_)' file
awk -F "" '{$1=toupper($1)}1' OFS= file
Explanation:
awk -F "" # set fieldseparator to "", now a field is one character
$1=toupper($1) # make the first character uppercase
1 # if the condition is true (1 = true) without an action, awk prints the current line per default
OFS= # set output field separator to ""
Thank you so much,
It's cool to write AWK code this way, but it's kinda tricky, I guess you are a BIG fan of Perl...
It would be more understandable written like this:
Note that the above only works for GNU sed.
My 2 cents:
$ var=abc
$ echo -n ${var:0:1} | tr -s '[:lower:]' '[:upper:]' && echo ${var:1}
Abc

My other 2 cents:
$ value=lowercase
$ echo ${value^?}
Lowercase
Search for section "Case modification" on bash's man page.
Seems to work only for bash >= 4.
