replace first semicolon occurence
Hi I have a logfile and I want to replace the first semicolon occurence, like:
head1;head2;head3;head4;head5
blabb;blabl;;blab;blabl;;bla
Desired output:
head1;head2;head3;head4;head5
blabb;blabl;blab;blabl;;bla
With regular expression how can select the first occurrence and replace for ";" I have the next command in sed:
sed -i 's/;;/;/g'
but this one replace all the occurrences file. Is there another way to do?
To make the substitution only act once, remove the `/g` modifier:
