Linux Bash Script: Custom delay code block (bare data save scheme)

In combination with alias and read usage, you can save some scripts that will be run late, or bare data (strings not being extended) into a variable for later use.

$ alias begin= ' read-d "" $ << "END" ' $ BEGIN block1> ls-la> end$ eval $block 1total 10drwxr-xr-x    1 Xiaoqia n administ     4096  5 22:42/drwxr-xr-x Xiaoqian administ     4096 Nov  5 22:31. /-rw-r--r--    1 Xiaoqian administ        3 Oct 16:26. gitignore-rw-r--r--    1 Xiaoqian administ 435      Oct 16:26 R Eadme.mddrwxr-xr-x    2 Xiaoqian administ        0 Nov  5 22:32 bin/-rwxr-xr-x    1 Xiaoqian administ      792 OCT 16:26 Meditate

Complete, in fact Block1 is a bare data, a BEGIN ... The end block contains any character text that you can understand asblock1= "Ls-la", but this ensures that the text is not extended by the shell engine.
