I have a long file with more lines than I fancy manually editing, and
need to cut all the added comments from any lines that have them.

ie:

line1
line2 # comments
line3
line4 # with notes
line5 # more stuff

....becomes

line1
line2
line3
line4
line5

Anybody got quick'n'simple technique for this kind of thing?

Something like:

sed 's/\([a-zA-Z0-9]*\)#.*/\1/g' -i file

don't forget to make a backup before you test.

'cut' should work quite nicely.

Load the file into vi and do command

:%s/#.*\n/^M/g

and all those comments disappear.

I get that ^M by doing Ctrl+v Ctrl+m

Try the following. That is assuming that your comments # is the first #
on each line:

sed -e 's/\(.*[^#]\)\(#.*\)/\1/' file.txt
