replace 2 identical strings on different lines
I am looking to replace two or more strings on different lines using sed, but not with the same variable. IE

Code:
# cat xxx.file
<abc>
abc def ghi
abc def ghi
abc def ghi

currently I can only change each line with the same pattern:
Code:
# sed -e '/<abc>/!s/abc\(.*\)/jkl mno/' xxx.file
abc jkl mno
abc jkl mno
abc jkl mno

I would like the output to be:

abc jkl mno
abc pqr stu
abc vwx yz

thanks

where did you get your "pqr stu" and "vwz yz" from?

this is the syntax I have been attempting:

Code:
sed -e '/<abc>/!1/abc\(.*\)/jkl mno/d' -e '2/abc\(.*\)/pqr stu/d' -e '3/abc\(.*\)/vwx yz/d' xxx.file

where 'pqr stu' and 'vwx yz' would be the 2nd and 3rd substitutions respectively.

nm, figured it out using the '[N]ext newline' syntax:

Code:
sed '/^abc\(.*\)/ {
N
N
s/abc\(.*\)/abc jkl mno\
abc pqr stu\
abc vwx yz/
}' xxx.file
