How to verify a checksum

Normally, you could just do:
| No Format |
|---|
| Note |
Unfortunately, the potential one-line solution: |
...
doesn't work because it incorporates the filename into the calculation. |
calculate the checksum:
| No Format |
|---|
$linux$ sha1sum -c commons-logging-1.0.4.jar.sha1 sha1sum:f029a2aefe2b3e1517573c580f948caac31b1056 *commons-logging-1.0.4.jar.sha1: no properly formatted SHA1 checksum lines found |
...
or
| No Format |
|---|
$macorlinux$ sha1sumopenssl dgst -sha1 commons-logging-1.0.4.jar f029a2aefe2b3e1517573c580f948caac31b1056 *SHA1(/Maven 2 Repo/commons-logging/commons-logging/1.0.4.jar |
And compare with the checksum:
| No Format |
|---|
$ cat /commons-logging-1.0.4.jar.sha1)= f029a2aefe2b3e1517573c580f948caac31b1056 |
...

If you're on Windows, Cygwin has the md5 and sha1 utilities: http://www.cygwin.com |
...
then compare with the externally supplied checksum:
| No Format |
|---|
$ cat commons-logging-1.0.4.jar.sha1
f029a2aefe2b3e1517573c580f948caac31b1056
