Compile a shell script program with a command line parameter, which is a file. #! /Bin/bash
# Script Name hypothesis: test. sh
If [[$ #-ne "1" |! -F $ *]; then
Echo "Usage:./test. sh parameter (enter a common file name )"
Exit 1
Fi
Uname = $ (ls-l $1 | awk '{print $3 }')
Ctime = $ (ls-l $1 -- full-time | awk '{print $6 }')
Echo "Owner: $ uname"
Echo "modification date: $ ctime"
Compile a shell program to bring a parameter to the runtime, and output all the data descriptions between the parameters in ascending order. A simple digital loop is provided.
Method:
N = $1
For (I = 1; 1 <= $ N; 1 ++ ))
Do
Echo $ I
Fi

Method 2:
N = $1
While (I <= $ N ))
Do
Echo $ I
(I ++) or I = 'expr $ I + 1' or let I ++ I only write three common + 1 Loops
Done

Method 3: The awk method is practical.
Awk 'in in {for (I = 1; I <100; I ++) print I }'

Method 4:
N = $1
Seq $1
Two rows of write scripts are

$1: The parameter in the running script is correct. Hope to help
