Re: [opensource-62] sed help

Hi mowgli,

Try this:

sed  '/^replacefromhereon$/,$d'  file.txt

'd' will delete all lines in this range: from the line matching 'replacefromhereon' and the end of the file ($). Note that the above will only output the changes to the terminal. To actually modify the file use the option '-i' (in place):

sed  -i  '/^replacefromhereon$/,$d'  file.txt

Hope it helps.
Pablo.

using sed (or awk or whatever is best/shortest command), how do i replace ALL the text from a matchedpattern to EOF in a file?

ie if the file is:

blahblahblah
moreblah
replacefromhereon
xxxx
.....
yyyy

and i want the file to be:

blahblahblah
moreblah
newtexthere
morenewtexthere.

except i wont know what all the text after "replacefromhereon" is.  so i need to replace from that matched pattern to EOF regardless of whats there.

how do i achieve in simplest way?
