Hi,
I could probably do at least part of this with an ed shell
script, but sed is probaly more standard. (I may have asked this
before, years back: FWIW. Anyhow, don't see it in my
~/Mail/freebsd files.)
How can I automagically delete from $1,155d AND from the
25th line from the bottom to the last line with sed? I spent
hours last night, by-hand saving web files; now I want to get rid
of the cruft from them.
Again, (I think) something like % sed -e 1,$155d filefoo
[[yes?]], but then the last part stumps me.
sed commands like 'd' take a pair of 'addresses'.
I don't know what $1,155 means, but if you mean delete the first 155
lines, then this should be easy:
sed -e '1,155d'
The second part (deleting the last 25 lines) may be slightly trickier,
as you don't know that you are going to hit end-of-file until you
actually hit it, so some sort of bufferring is required :-/
