To upper case every char after space
awk '{ for ( i=1; i <= NF; i++)
{ sub(".", substr(toupper($i),1,1) , $i) }
print }' infile
{ sub(".", substr(toupper($i),1,1) , $i) }
print }' infile
How can you convert a text file to all lower case or all upper case?
As usual, in Linux, there are more than 1 way to accomplish a task.
To convert a file (input.txt) to all lower case (output.txt), choose any ONE of the following:
* dd
$ dd if=input.txt of=output.txt conv=lcase
* tr
$ tr '[:upper:]' '[:lower:]' < input.txt > output.txt
* awk
$ awk '{ print tolower($0) }' input.txt > output.txt
* perl
$ perl -pe '$_= lc($_)' input.txt > output.txt
* sed
$ sed -e 's/\(.*\)/\L\1/' input.txt > output.txt
We use the backreference \1 to refer to the entire line and the \L to convert to lower case.
To convert a file (input.txt) to all upper case (output.txt):
* dd
$ dd if=input.txt of=output.txt conv=ucase
* tr
$ tr '[:lower:]' '[:upper:]' < input.txt > output.txt
* awk
$ awk '{ print toupper($0) }' input.txt > output.txt
* perl
$ perl -pe '$_= uc($_)' input.txt > output.txt
* sed
$ sed -e 's/\(.*\)/\U\1/' input.txt > output.txt
