我试图让用户从编号列表中选择两个文件,该列表源自目录列表,最终将变成一个变量。我只是一名网络工程师,试图自动组合来自交换机的一些显示输出命令。
这是我所拥有的不起作用的:
echo "Please Select the Show interface status file"
select FILE1 in *;
echo "Please Select the Show Vlan file"
select FILE2 in *;
do
当我能够从目录中选择文件时,我计划“cat $FILE1 > file1”和“cat $FILE2 > file2”,然后我将组合它们。
答案1
每一项select
陈述都需要先完成,然后才能继续下一项陈述。语句select
实际上是一种特殊类型的循环。
假设我有一组文件,examplefile01
通过examplefile10
.如果我有这样的脚本:
select f in example*; do
echo "You selected $f"
break
done
在执行中它看起来像这样:
$ ./470595.sh
1) examplefile01 4) examplefile04 7) examplefile07 10) examplefile10
2) examplefile02 5) examplefile05 8) examplefile08
3) examplefile03 6) examplefile06 9) examplefile09
#? 5
You selected examplefile05
该break
语句很重要,因为否则该select
语句将循环返回以再次呈现选项。
因此,就你的情况而言,你可能需要类似以下的东西:
echo "Please Select the Show interface status file"
select FILE1 in *; do
cat "$FILE1" >> outputfile1
break
done
echo "Please Select the Show Vlan file"
select FILE2 in *; do
cat "$FILE2" >> outputfile2
break
done
您还可以聪明一点,通过设置 PS3echo
修改语句提供的提示来避开这些语句:select
PS3="Please Select the Show interface status file )"
select FILE1 in *; do
cat "$FILE1" >> outputfile1
break
done
PS3="Please Select the Show Vlan file )"
select FILE2 in *; do
cat "$FILE2" >> outputfile2
break
done
此外,由于您计划合并文件,因此在最终选择的同时进行可能会更容易:
PS3="Please Select the Show interface status file )"
select FILE1 in *; do
break
done
PS3="Please Select the Show Vlan file )"
select FILE2 in *; do
cat "$FILE1" "$FILE2" > outputfile
break
done

感谢您的帮助,我能够让它工作。它不漂亮,但它满足了我的要求
#Combine Show Vlan and Show interface status Function
combinevlanshint()
{
cd $shintstatvlan
clear
#Ask for Hostname
echo "Names can not contain spaces:"
echo " "
echo "Please enter the Hostname"
read "hostname"
clear
echo "Please Select the Show interface status file"
select FILE1 in *; do
cat "$FILE1" > $shintstatvlan/file1
break
done
echo "Please Select the Show Vlan file"
select FILE2 in *; do
cat "$FILE2" > $shintstatvlan/file2
break
done
echo "You picked $FILE1 and $FILE2 , These files will now be combined. Press any key to continue"
read -n 1
cat $FILE1 > file1
cat $FILE2 > file2
