removing characters
Hi all,
Any help on how to do the following?
I have an infile as follows:
_thisishowyouwritehelloworld
_thisisalsohowyouwritehelloworld2
I want to delete the characters from "_" to "how" and be left with:
youwritehelloworld
youwritehelloworld2
I am able to do delete from a string to the end of a line like this:
sed 's/how.*$//' infile > outfile
But I want to delete from the beginning of a file to a chosen string
Thankyou in advance for any help
Layla
