getting an error in Linux when try to create a file or save

Hi
I was trying to create file in Linux but getting error as shown below:
$ cat > file
-bash: file: Read-only file system
Hope will get better solution.
Thanks in advanced.

 

My guess: current directory when doing cat > file is not writable. The error messages says Read-only file system. What shows

Code:

cat > file
pwd
df -hT .

If you just want to cat to somewhere, this should work:

Code:

cat > /tmp/file.txt

Press Control-D when finished writing to that file.
