"Less" command not working

I noticed that the “less” command is not working, simply not returning anything. The program is there:

root@MusicBox:/# which less

but is doesn’t give any output:

root@MusicBox:~# less updatepip.py

I have found the reason: the command was simply missing!

/bin/less was a 0 bytes file. I have copied the file from another raspian and now less is back again!

Strange. I haven’t tinkered too much with my PiMusicBox and it’s got the correct and complete version of /bin/less . Considering this and the odd search performance you reported, perhaps you’ve got a bad SD card?

Don’t know. The card is new and it is perfectly working…
The search is now working by limiting the search to specific service.
