How can I grep / awk this?
advertisements
I'm pretty new to Linux and I'm still learning the commands. All I want to do is format my .txt file.
Here is what my file looks like:
hello hello
goodbye goodbye
random random
example example
last last
All I want to do is remove the space and replace it with a semi-colon.
For example:
hello:hello
goodbye:goodbye
random:random
example:example
last:last
I'm not sure what command will accomplish this task, I'm pretty sure it's grep or awk. It would be great if someone can help me out on this. Thanks, all help is appreciated.
sed is the simplest tool for this task:
sed 's/ /:/' infile > outfile
