How to put space between these two words without affecting other words.
As you can see, I have two columns here adjusted in decreasing order of age. I want to separate the word NameAge so that each of them be in a cell and its corresponding column. How can I solve this problem?
The command below insert space between lowercase letter and uppercase letter.
sed '1s/\([a-z]\)\([A-Z]\)/\1 \2/g' orig.txt > split.txt
orig.txt:
NameAge Bob 90 Sarah 76 Russel 49 Kate 21
split.txt
Name Age Bob 90 Sarah 76 Russel 49 Kate 21
EDIT: 1 in the sed expression to affect only header, per suggested by @jm666
EDIT2:
sed '1s/-/ /g' orig.txt > split.txt
Turned out that orig.txt looks like this:
Name-PersonNumber-Age Bob 1 90 Sarah 2 76 Russel 3 49 Kate 4 21
split.txt
Name PersonNumber Age Bob 1 90 Sarah 2 76 Russel 3 49 Kate 4 21
