#! /Bin/sh

[$ #! = "1"] & echo "Usage: $0 tarfile" & exit 0

DESTFILE = "$ 1.sh"

Echo "#! /Bin/sh "> $ DESTFILE

Echo "LINES = \ 'wc-l \ $0 | awk '{print \ $1}' \ '"> $ DESTFILE # calculates the number of rows of the target file

Echo "LINES = \ 'expr \ $ LINES-4 \ '"> $ DESTFILE # Calculate the row to be output, which is the total number of rows-4 (4 rows run the script)

Echo "tail-n \ $ LINES \ $0 | tar-xv"> $ DESTFILE # output and release (compressed files can be released in combination with-z/-j)

Echo "exit 0" >>$ DESTFILE

Chmod + x $ DESTFILE

Cat $1 >>$ DESTFILE # Add the tar file to the end of the file
