You can set the internal field separator (IFS) variable, and then let it parse into an array. When this happens in a command, then the assignment to IFS
only takes place to that single command’s environment (to read
). It then parses the input according to the IFS
variable value into an array, which we can then iterate over.
This example will parse one line of items separated by ;
, pushing it into an array:
IFS=';' read -ra ADDR <<< "$IN" for i in "${ADDR[@]}"; do # process "$i" done
This other example is for processing the whole content of $IN
, each time one line of input separated by ;
:
while IFS=';' read -ra ADDR; do for i in "${ADDR[@]}"; do # process "$i" done done <<< "$IN"
