shell script/command for converting columns/table onto a single line
Hi all,
I'm after a command, or a sequence of commands that can help me convert values in a table (columns and rows) to values on a single line. The number of columns in the input file is always the same but the number of rows can vary.
eg
The table might look like the following:
A B C
D E F
G H I
J K L
I need the information to be output onto a single line that looks like the following.
The "cat file | tr '\n' ' ' >newfile" example will add a space after the last item if the last lines ends with a newline as is apt to be the case.
The 2nd post isn't taking the input from a file.
The "file=$(<yourfile); echo $file < newfile" example works perfectly.
I think the 2nd post showing the difference between $a and "$a" and the later one completed it by entering the file into a variable:
a=$(<temp)
~> echo "$a" >newfile
A B C
D E F
G H I
K L M
N O P
~> echo $a >newfile
A B C D E F G H I K L M N O P
