I've looked around AskUbuntu, as well as just trying on the internet; but i can see no solution, every time i change my coding.
I run Ubuntu 18.04.1 (in case that matters)
and i want to have a simple script that will allow data to be added to a file, but if the file already exists, to allow it to continue from where it left off at the beginning.
so i want file to be created and the first piece of information put into it from a 3rd party source.
then i want now that the file already exists, i want it to add new information at the bottom of the existing text
for egg sample
- the file does not exist
- a file is created (called "mylog")
- information is added to the first line of the file and a newline is
created to move the cursor to the beginning of the next available
line. - The file contains all the log information i needed by monitoring them
for me - while i learn sleep patterns again.
Is this even possible on Ubuntu, Am I missing the obvious; the irony is that i can do it in DOS with my eyes closed.
Thanks in advance; please refer to similar questions if you think they will help, i personally was just not able too.
I've been trying to do it with gedit and a terminal to run it each time to test. If you can do it with bash, that would be great, if you think something better, that's perfectly acceptable, i Just use Bash because it's my favourite, but I'm not married to it.
