Replace all spaces by,

Hi,

Can I get a perl script that can convert the following output into CSV. So basically all the spaces need to be converted to a comma.

My goal is to run a cron job every day and then add the output of df-h into a CSV file every day. I need to script.

Script 1 will just convert this output to CSV

Script 2 will open a file everyday for append and then it will issue the df -h command then store the output of df -h into a CSV file everyday  and it will skip the headers. Also can the perl script get the hostname of the machine also and then add it as a column to the csv and repeat the hostname in the CSV every day ?



thanks

Easiest way to skip the first line is to just pipe the df output first to tail +2

df -h | tail +2 | perl -lpe 's/\s+/,/g'

[root@myserver ~]# df -h | tail +2 | perl -lpe 's/\s+/,/g' > x1.txt
tail: cannot open `+2' for reading: No such file or directory

Sorry, tail +2 doesn't work for every version of tail.

You should be able to use:

df -h | tail --lines=+2 | perl -lpe 's/\s+/,/g'

Or:

df -h | egrep -v "^Filesystem"| perl -lpe 's/\s+/,/g'


Ozo's last comment seems to address your need, though when I try it it adds an extra comma to the end of the first line.
