If there is nothing sensitive in the data file, why not attach it to a post so that everyone can examine it? Or, remove extraneous lines until you have created a minimal file, free of sensitive information, that still "misbehaves" when grepped, and attach that. In either case, do not copy/paste as that can modify the data.
If you do attach a file, please make sure to mention which operating system you are using? And, if you know, which implementation of grep (if this is a linux system or cygwin, it's almost certainly gnu's grep).
Alternative ways to search a file for a word include sed, awk, sh read/case glob, perl, python, ... etc. Although, if that were my file, I'd really want to know what is going on. Without knowing what's going on, you could be experiencing other false negatives and not even know it.
Regards,
Alister

devfs(7FS) File Systems devfs(7FS)
NAME
devfs - Devices file system
DESCRIPTION
The devfs filesystem manages a name space of all devices under the Solaris operating environment and is mounted during boot on the /devices
name space.
The /devices name space is dynamic and reflects the current state of accessible devices under the Solaris operating environment. The names
of all attached device instances are present under /devices.
The content under /devices is under the exclusive control of the devfs filesystem and cannot be changed.
The system may be configured to include a device in one of two ways:
By means of dynamic reconfiguration (DR), using, for example, cfgadm(1M).
For devices driven by driver.conf(4) enumeration, edit the driver.conf file to add a new entry, then use update_drv(1M) to cause
the system to re-read the driver.conf file and thereby enumerate the instance.
The device may be attached through a number of system calls and programs, including open(2), stat(2) and ls(1). During device attach, the
device driver typically creates minor nodes corresponding to the device via ddi_create_minor_node(9F). If the attach is successful, one or
more minor nodes referring to the device are created under /devices.
Operations like mknod(2), mkdir(2) and creat(2) are not supported in /devices.
FILES
/devices Mount point for devfs file system
SEE ALSO
devfsadm(1M), vfstab(4), attach(9E)
NOTES
The /devices name space cannot be unmounted.
All content at or below the /devices name space is an implementation artifact and subject to incompatible change or removal without notifi-
cation.
