I have the following string stored in a Bash variable:
string="Doe, Jane;Smith, John;Bloggs, Joe"
How can I split this string on the ;
delimiter in Bash?
To split the string in this variable, we can temporarily set Bash’s input field separator variable (IFS
) to the desired delimiter while reparsing it into an array read -ra
. For example:
string="Doe, Jane;Smith, John;Bloggs, Joe" IFS=";" read -ra names <<<"$string" for name in "${names[@]}"; do echo "$name" done
This code will produce the following output:
Doe, Jane Smith, John Bloggs, Joe
In our read
command, the -a
flag creates an array, and the -r
flag prevents backslashes from escaping any characters in the string.
A simpler way to achieve this would be to use the cut
command, but this requires us to know the number of elements in the string, which may not be possible in all cases. The code below produces the same output using cut
instead of IFS
:
string="Doe, Jane;Smith, John;Bloggs, Joe" for index in {1..3}; do echo "$string" | cut -d ";" -f $index done
