I wanted to extract a list of numbers (string.txt) from masterFile.list. masterFile.list is separated by '|' and contained more than one column. I am only interested with the line, where its first column contained number matched in the string.txt file.

string.txt:

3075
3078
3076

masterFile.list

3078    |       Auxenochlorella pyrenoidosa (H.Chick) Molinari & Calvo-Perez, 2015      |       
         |       authority       |
3079    |       Auxenochlorella pyrenoidosa 3078    |               |       scientific name |
3076    |       Chlorella pyrenoidosa H.Chick, 1903     |               |       authority       |
3077    |       Chlorella vulgaris var. viridis Chodat, 1913    |               |       authority

460     |       DSM 23076       |       DSM 23076 <type strain> |       type material   |

expected output:

Most of the previous post I have found only allow the extraction of single string, and limit match to first column. Is it possible to extract more than one string at a time?
