# version_compare
```
usage: version_compare {{v} | {v1} {operator} {v2}}
{v} execution example:
version_compare "1.2.3 > 1.2.3"
0
version_compare "1.2.3 >= 1.2.3"
1
version_compare "1.2.3 < 1.2.3"
0
version_compare "1.2.3 <= 1.2.3"
1
version_compare "1.2.3 != 1.2.3"
0
version_compare "1.2.3 = 1.2.3"
1
{v1} {operator} {v2} execution example:
version_compare "1.2.3" ">" "1.2.3"
0
version_compare "1.2.3" ">=" "1.2.3"
1
version_compare "1.2.3" "<" "1.2.3"
0
version_compare "1.2.3" "<=" "1.2.3"
1
version_compare "1.2.3" "!=" "1.2.3"
0
version_compare "1.2.3" "=" "1.2.3"
1
```
## Example
```shell
#!/usr/bin/env bash
v1=1.0.0
v2=1.0.1
op='>='
result=$(version_compare "$v1 $op $v2")
if [ -z "$result" ]; then
# operation failed
exit 1
fi
if (( result )); then
# operation true
else
# operation false
fi
