Simple REGEX

[Gabriel]

Hello.
I have a file with this kind of data:

field1;field2;field3;field4\n

For example:

Andrew;Dimmu;Shagrath big;This is correct; /* CORRECT LINE */
Jeny; Hello Jen; Spaces;Black; /* INCORRECT LINE */

How can I delete those first spaces (Jeny;Hello Jen;Spaces;Black) ?
$line =~ /;[ ]+//g; ?

I have a file with this kind of data:
field1;field2;field3;field4\n
Andrew;Dimmu;Shagrath big;This is correct; /* CORRECT LINE */
Jeny; Hello Jen; Spaces;Black; /* INCORRECT LINE */

How can I delete those first spaces (Jeny;Hello Jen;Spaces;Black) ?
$line =~ /;[ ]+//g; ?

perl -lpe 's/(?<=\s+|^\s+|\s+(?=//g' file.txt

This works in these cases:

|
Jeny; Hello Jen; Spaces;Black;
Jenny Space Front; Hello Jen ; Spaces;Black;
Andrew;Dimmu;Shagrath big;This is correct;
|

Regards

M.

Almost, but that deletes the semi-colon as well, so you have to put
that one back in:

$line =~ s/; +/;/g;

Just an amendment. This will not work with a space in the first field (read:
beginning of the line).



s/( +|^ +/$1/g;
