Question

I am not sure how do this, so I need some help,
I am working on a file and need to extract only some substrings of this file.
Each linea is separated by semicolons ;
I would only need the first field, and another field.
Something similar as follows:

Input File:

nakamed;   ecd.bat  ;\\DomainD\userhome_n\nakamed;"\\DomainD\userhome_n\nakamed";"\\serverfile66\userhome\nakamed";"Migrated from standalone DFS"
tanreka;   ecd.bat serverfile60_D  ;;
tayljka;   ecd.bat  ;\\DomainD\userhome_t\tayljka;"\\DomainD\userhome_t\tayljka";"\\serverfile47\userhome_d\tayljka";"Migrated from standalone DFS"
taylpoo;   ecd.bat  ;\\DomainD\userhome_t\taylpoo;"\\DomainD\userhome_t\taylpoo";"\\serverfile32\userhome\taylpoo";"Migrated from standalone DFS"
thomcet;   ecd.bat  ;\\DomainD\userhome_t\thomcet;"\\DomainD\userhome_t\thomcet";"\\serverfile32\userhome\thomcet";"Migrated from standalone DFS"
thomdop;   ecd.bat  ;\\DomainD\userhome_t\thomdop;"\\DomainD\userhome_t\thomdop";"\\serverfile66\userhome\thomdop";"Migrated from standalone DFS"

Desired Output file:

nakamed;   serverfile66
tanreka;   serverfile60
tayljka;   serverfile47
taylpoo;   serverfile32
thomcet;   serverfile32
thomdop;   serverfile66

Answer 1

Try doing this using sed :

sed -r 's/^([a-zA-Z0-9]+);.*(serverfile[0-9]+).*/\1;   \2/' file.txt

Or with awk :

awk '{print $1, " ", gensub(/.*(serverfile[0-9]+).*/, "\\1", $0)}' file.txt

OUTPUT

nakamed;   serverfile66
tanreka;   serverfile60
tayljka;   serverfile47
taylpoo;   serverfile32
thomcet;   serverfile32
thomdop;   serverfile66
