While in a Linux shell I have a string which has the following contents:
cat dog bird and I want to pass each item as an argument to another function. How can I do this?

The (&&) and (;) can execute a multi-line code that runs commands that are dependent and then independent of previous statements. A subshell can include commands listed within curly braces or the EOF tag. Curly braces could include a subshell and/or EOF tag. The EOF tag can include subshells and curly braces.
To add multiple lines to a file with echo, use the -e option and separate each line with \n. When you use the -e option, it tells echo to evaluate backslash characters such as \n for new line. If you cat the file, you will realize that each entry is added on a new line immediately after the existing content.
Use echo With the -e Option to Make Multi-Line String in Bash. The following bash script prints the words to multiline. txt without any extra spaces. The -e option enables the interpretation of escape characters in the variable greet .
Use this (it is loop of reading each line from file file)
cat file | while read -r a; do echo $a; done where the echo $a is whatever you want to do with current line.
UPDATE: from commentators (thanks!)
If you have no file with multiple lines, but have a variable with multiple lines, use
echo "$variable" | while read -r a; do echo $a; done UPDATE2: "read -r" is recommended to disable backslashed (\) chars interpretation (check mtraceur comments; supported in most shells). It is documented in POSIX 1003.1-2008 http://pubs.opengroup.org/onlinepubs/9699919799/utilities/read.html
By default, unless the -r option is specified,
<backslash>shall act as an escape character. .. The following option is supported:-r- Do not treat a<backslash>character in any special way. Consider each to be part of the input line.
