Cmd List

Command Lists

• { [command list]; }
• Execute the list of commands in the current shell as though they were one command.
• Command grouping on its own isn't very useful. However, it comes into play wherever Bash syntax accepts only one command while you need to execute multiple.
• For example, you may want to pass output of multiple commands via a pipe to another command's input:

{ ls .; ls ..; } | grep file-name

• Or you may want to execute multiple commands after a || operator:

rm file || { echo "Removal failed, aborting."; exit 1; }

• It is also used for Funcs bodies. Technically, this can also be used for loop bodies though this is undocumented, not portable and we normally prefer do ...; done for this):

for digit in 1 9 7; { echo "$digit"; }       # non-portable, undocumented, unsupported
- for digit in 1 9 7; do echo "$digit"; done   # preferred

• *Note: You need a ; before the closing } (or it must be on a new line).
• Command Lists are similar but not identical to
