Bash Version: 5.2 Patch Level: 15 Release Status: release ####################################################### Process substitution can be used in place of a file in a command line as follows: bash$ cat test.jl for a in ARGS println(a) end bash$ julia test.jl 11 22 33 11 22 33 bash$ julia <( cat <<\@ for a in ARGS println(a) end @ ) 11 22 33 11 22 33 However, in the above method, the 11 22 33 arguments are placed at the end of the command line, which is not good for readability. So writing the following would make the command line much more readable, but it would output unnecessary warning messages. bash$ julia <( cat <<\@ ) 11 22 33 for a in ARGS println(a) end @ bash: warning: command substitution: 1 unterminated here-document 11 22 33
