Bash (Linux) and Powershell (Windows) Scripts to Test File Access to Multiple Locations

Linux

Here’s the bash script with 2 example targets:

#!/bin/bash

while true

do

([ -e /mnt/test1/test1.txt ] && date >> /mnt/LOG/log1.txt || echo "FAILURE")

([ -e /mnt/test2/test2.txt ] && date >> /mnt/LOG/log2.txt || echo "FAILURE")

sleep 1

done

Save as say fileaccess.sh and run in bash as sh fileacess.sh

In the above example we’re testing access to 2 files, each in a different mount point. Time stamp is log for successes. Failure is echoed to the screen for failure. There’s a wait of 1 second.

It’s possible to do it as a one line to from the bash shell:

while true ; do ([ -e /mnt/test1/test1.txt ] && date >> /mnt/LOG/log1.txt || echo "FAILURE") ; ([ -e /mnt/test2/test2.txt ] && date >> /mnt/LOG/log2.txt || echo "FAILURE"); sleep 1 ; done

Powershell

Here’s the powershell script with 2 example targets:

"" > C:\LOG\log1.txt

"" > C:\LOG\log2.txt

while($TRUE){

If (test-path C:\mnt\test1\test1.txt){ [String](date) >> C:\LOG\log1.txt }

else { Write-Host "FAILURE" }

If (test-path C:\mnt\test2\test2.txt){ [String](date) >> C:\LOG\log2.txt }

else { Write-Host "FAILURE" }

sleep 1

}

Save as say filetester.ps1 and run in powershell .\filetester.ps1

Similarly, you could turn it into a one liner. Or you can just copy and paste it into powershell.

Intention

The idea is that you can set up a number of NFS mounts, and/or a number of CIFS shares, and test the availability of file access.
