shell中如何比较 路径 字符串？

[hzgdiyer]

比如A字符串：/users/ricky/0220/app1
我获取了另外一个路径字符串B，如何比较A B 是否相同？

if [[ "$A" -eq "$B" ]];then
echo "same path"
else
echo "diff path"
fi

报错： arithmetic syntax error， 应该是路径中有特殊字符/的原因，各位有什么好办法吗？

A="/users/ricky/0220/app1";B="/users/ricky/0220/app1";if [[ "$A" == "$B" ]];then echo "same path"; else echo "diff path"; fi

不是-eq，是==

字符串比较用=即可，数字才用-eq

多谢。

For Mathematics, use following operator in Shell Script
Mathematical Operator in Shell Script Meaning Normal Arithmetical/ Mathematical Statements But in Shell
For test statement with if command For [ expr ] statement with if command
-eq is equal to 5 == 6 if test 5 -eq 6 if [ 5 -eq 6 ]
-ne is not equal to 5 != 6 if test 5 -ne 6 if [ 5 -ne 6 ]
-lt is less than 5 < 6 if test 5 -lt 6 if [ 5 -lt 6 ]
-le is less than or equal to 5 <= 6 if test 5 -le 6 if [ 5 -le 6 ]
-gt is greater than 5 > 6 if test 5 -gt 6 if [ 5 -gt 6 ]
-ge is greater than or equal to 5 >= 6 if test 5 -ge 6 if [ 5 -ge 6 ]


For string Comparisons use
Operator Meaning
string1 = string2 string1 is equal to string2
string1 != string2 string1 is NOT equal to string2
string1 string1 is NOT NULL or not defined
-n string1 string1 is NOT NULL and does exist
-z string1 string1 is NULL and does exist

Shell also test for file and directory types
Test Meaning
-s file Non empty file
-f file Is File exist or normal file and not a directory
-d dir Is Directory exist and not a file
-w file Is writeable file
-r file Is read-only file
-x file Is file is executable
