Question

I need to remove the character : from a file. Ex: I have numbers in the following format:

b3:07:4d

I want them to be like:

b3074d

I am using the following command:

grep ':' source.txt | sed -e 's/://' > des.txt

I am new to Linux. The file is quite big & I want to make sure I’m using the write command.

Answer 1

You can do without the grep:

sed -e 's/://g'  source.txt > des.txt
