Delete Multiple rwx entries in Flash in one command on Cisco 3750x

[anthonywilson5]

I wanted to know if there was a single command to delete multiple rwx entries on a Cisco 3750x Switch. I am trying to free up space. I am aware of the delete flash:/(file name) command but am not able to find a batch delete command for these entries. These are the following that I would like to remove without having to do them individually.

I am new to Cisco so please respond with an answer that is understandable. Thank you in advance for your time and assistance.

Hi

unfortunately not , you would have to wipe the whole flash through format you could do that then re-upload the ios , the only other way is line per line

[anthonywilson5]

Thank you sir for your quick response.

Not really. Some of the newer flash/file-systems allow you to use wildcard. Here is an example:

Switch#delete flash:run-*
Delete filename [run-*]?
Delete flash:/run-1? [confirm]
Delete flash:/run-2? [confirm]
Delete flash:/run-3? [confirm]
Delete flash:/run-4? [confirm]
Switch#delete flash:run-*
Delete filename [run-*]?
No such file
Switch#

For this purpose, I created four files of the running-config and named them as run-1 through run-4. Then, proceeded to use delete flash:run-* Notice that after fourth [confirm], all files that matched the run-* were deleted from the flash:.


Anthony - IOS has been around for little over 30 years. Things change quite a bit. Back in the day, when flash development was primitive, there were quite a few limitations including very very slow ready/write performance. This does not mean things remain the same.

I like the way you posed the question - including evidence of the problem/question. This is extremely helpful. Since you say you are new, the authoritative answers are often found by trying it out for yourself, especially for non-destructive testing like this one.

Here is another variation using wildcard:

Switch#delete flash:*Conf*
Delete filename [*Conf*]?
Delete flash:/Oct-Conf? [confirm]
Delete flash:/Nov-Conf-1? [confirm]
Delete flash:/Dec-Conf-2? [confirm]
Switch#

Taking this to your situation, to delete the files selectively, please consider trying delete flash:*E?T*. I don't know what's is going to happen, but worth trying, right? :-)

Since delete is a destructive operation, consider issuing dir flash:*E?T* and see if the results are the files you want to delete.

Kind regards ... Palani

PS The above attempts were tried in this device:

Switch#show ver | i IO
Cisco IOS Software, C3750E Software (C3750E-UNIVERSALK9-M), Version 15.2(4)E1, RELEASE SOFTWARE (fc2)
Switch#

Kind regards .... Palani

Hello, I had the same question on removing those files. What I'm concerned with is the type of file I'm deleting and what generated it. The files displayed in the question look very similar to the files on some of our switches. They appear right after we make changes to the switch so figured it's a log file of some sort. I've checked against other configurations on our network but don't see anything that could turn that functionality on as we send all files to a syslog server. Would you happen to be aware of any settings that would generate these types of files? I was looking into SNMP-server traps for a clue.

Good man! Saved me an hour of deleting pcm.datX files
Used delete flash:/pcm.datX*
Much thanks,
Jace

Thanks! This worked for me! I had a lot of archive files to delete, so using the delete flash:*wildcard* command helped me delete like 6 million archive files. Lol.
