I can't do "cd /user/vbhaarat90/" while practicing Flume commands


I can’t do “cd /user/vbhaarat90/…” is it because of the permissions? If Yes, how can run the code to get the web server logs to hdfs?​
I am not able to practice things related to Flume. I created the directory at the following location as I can’t do cd /user/vbhaarat90/…
Path: cd /home/vbhaarat90/flume_demo/wslogstohdfs/
I get the following errors while I ran the flume-ng command:
Command: flume-ng agent -n wh -f /home/vbhaarat90/flume_demo/wslogstohdfs/wshdfs.conf
