Remove text from file after only a specific match

Question

I have a file with multiple occurances of a string, I need to remove only one of the occurrences using a specific match. I cannot seem to get a good way of doing this, i keep removing all occurrences

sed -i "s/|item2//g"

file format:

 "1234567890|item2",
 "1234567895|item2",
 "3454343345|item1|item2",
 "7854343345|item1|item3",
 "0454343555|item1|item4|item6",

What i need to do is to match the first set of numbers say 3454343345 then after this remove a specific string, like item2.

Output I am trying to get

 "1234567890|item2",
 "1234567895|item2",
 "3454343345|item1|",
 "7854343345|item1|item3",
 "0454343555|item1|item4|item6",

Answer 1

Try this,

 sed -e '/^"3454343345/ s/item2//' file

"1234567890|item2",
"1234567895|item2",
"3454343345|item1|",
"7854343345|item1|item3",
"0454343555|item1|item4|item6",

• Replace -e with -i to edit inline, if the output matches your desired result.
