Running ripgrep gives IO and invalid argument errors

Installed via yum on RHEL 7.5
Not sure if I missed something?

$ sudo rg -l '123-?45-?6789' /

Dunno, sorry. Works on my system, and ripgrep is issuing standard syscalls:

$ rg foobar mem
mem: Permission denied (os error 13)
$ sudo rg foobar mem
$ sudo rg foobar mem --no-mmap
$ sudo rg foobar mem --mmap
$

Does the same problem occur with grep?

Also, it is a really bad idea to search / with sudo. There are issues where people have tried this before. The /proc and /dev directories in particular can be tricky, where even reading a file as root and cause a state change on your system.

[CrookedJ]

Oh. That's actually fine then.
Instead, I'll just search specific directories, I don't necessarily need to search /proc, I just was trying to do an entire file system search in one command.

$ sudo rg -l '123-?45-?6789' /home runs fine, I can just run it for all the other directories.

@CrookedJ For clarity, does grep produce the same error messages when searching /proc?

[CrookedJ]

Pretty much the same I'd say.

$ sudo grep -l -r '123-?45-?6789' /proc
grep: /proc/fs/nfsd/unlock_filesystem: Invalid argument
grep: /proc/fs/nfsd/unlock_ip: Invalid argument
grep: /proc/fs/nfsd/filehandle: Invalid argument
grep: /proc/sys/net/ipv4/route/flush: Permission denied
grep: /proc/sys/net/ipv6/conf/all/stable_secret: Input/output error
grep: /proc/sys/net/ipv6/conf/default/stable_secret: Input/output error
grep: /proc/sys/net/ipv6/conf/enp3s0f0/stable_secret: Input/output error
grep: /proc/sys/net/ipv6/conf/enp3s0f1/stable_secret: Input/output error

Aye, that's what I would expect. It's definitely not an issue with ripgrep, but I don't know what the difference is between your system and mine. Maybe you have something like SEL enabled? Dunno.

[CrookedJ]

Possibly? To be honest, I'm not super familiar with Linux - just trying to complete some tasks for work.
And clearly not familiar enough to realize /proc isn't something I should be searching, heh.

Thank you though
