# The `cmp` command
|
|
|
|
The `cmp` command is used to compare the two files byte by byte.
|
|
|
|
Example:
|
|
```
|
|
cmp file1.txt file2.txt
|
|
```
|
|
|
|
Syntax:
|
|
```
|
|
cmp [option] File1 File2
|
|
```
|
|
|
|
## Few Examples :
|
|
|
|
1. ### Comparison of two files:
|
|
|
|
Perform a simple comparison of the two files to check out if they differ from each other or not.
|
|
|
|
Example:
|
|
```
|
|
cmp File1 File2
|
|
```
|
|
|
|
2. ### Comparing Files after Skipping a Specified Number of Bytes:
|
|
|
|
Compare two files after skipping a certain number of bytes
|
|
|
|
Example:
|
|
```
|
|
cmp -i 2 list.txt list2.txt
|
|
```
|
|
|
|
Here “INT” represents the number of bytes to be skipped
|
|
|
|
3. ### Display the Differing Bytes of the Files in the Output:
|
|
|
|
Example:
|
|
```
|
|
cmp -b list.txt list1.txt
|
|
```
|
|
4. ### Display Byte Numbers and Differing Byte Values of the Files in the Output:
|
|
|
|
Example:
|
|
```
|
|
cmp -l list.txt list1.txt
|
|
```
|
|
|
|
5. ### Comparing the First “n” Number of Bytes of the Files:
|
|
|
|
Example:
|
|
```
|
|
cmp -n 10 list.txt list2.txt
|
|
```
|
|
### Additional Flags and their Functionalities
|
|
|
|
|**Short Flag** |**Long Flag** |**Description** |
|
|
|:---|:---|:---|
|
|
|`-b`|`--print-bytes`|print differing bytes|
|
|
|`-i`|`--ignore-initial=SKIP`|skip first SKIP bytes of both inputs|
|
|
|`-i`|`--ignore-initial=SKIP1:SKIP2`|skip first SKIP1 bytes of FILE1 and first SKIP2 bytes of FILE2|
|
|
|`-l`|`--verbose`|output byte numbers and differing byte values|
|
|
|`-n`|`--bytes=LIMIT`|compare at most LIMIT bytes|
|
|
|`-s`|`--quiet, --silent`|suppress all normal output|
|
|
|`v`|`--version`|output version information and exit|
|
|
||`--help`|Display this help and exit|
