bash脚本IFS=',' read的意思

• IFS is the Input Field Separator, which means the string read will be split based on the characters in IFS. On a command line, IFS is normally any whitespace characters, that‘s why the command line splits at spaces.

the canonical way to read one line of input with the read builtin is:

IFS= read -r line

如： IFS=‘,‘ read -ra DEPS <<< ${dependencies}
