Need help replacing a work in a file with a variable plus a word.

[cden2]

I am a new to scripting. I am working with a script to replace the
word 'name' in a file with the name of the server. I am trying pass a
variable in a search and replace command using sed. It works now, but
only replaces the word 'name' with the '${SERVER}: name' and not the
actual hostname.

TMPDIR="/rae/tmp"
SERVER="`hostname`"

sed -i 's/name:/${SERVER}: name/g' $TMPDIR/mounts.$SERVER

Currently in file
------------------------

name: chris

Trying to make the output to the file mounts.$SERVER become:
-------------------------------------------------------------------------------------------

cltgap01: name: chris

Could awk or gawk work better for this? Please help.

Thanks,
Chris

use double quotes instead of single quotes

PDreyer!!! Thanks for your help it works. I am in the final stage of the script.

Question 1:

The output is created in a file called reportmounts which is appended with the DATE.TIME.

I want to email the latest DATE.TIME stamped file content view email to an address.

How do I script this?

directory: /rae/tmp contains

reportmounts.091230.0825
reportmounts.091230.0830
reportmounts.091230.0840
reportmounts.091230.0950

I want the last reportmouts file to be emailed.

Chris

Thanks!!! that worked. It brought about an issue.

lastfile="$( ls -1tr /rae/tmp/reportmounts.*.* | head -1 )"

works, but if it is the first file being put in the directory, it says no $lastfile exist. So I am trying to create an if statement that will check else just use the existing file.

2)I also want to put a statement at the end of the script to have it run every 5 minutes. The output file will pile up, so I am going to try and script it to delete the prior day mounts. The files should not be that large.

Let me know if you can help.

THanks,
Chris

Hi

works, but if it is the first file being put in the directory, it says no $lastfile exist.

I do not understand this. You are running that code after a reportmounts file was created, right ? ( By the way, how is that created ? ) So there must be at least one. So there is no reason for that code to complain.

I also want to put a statement at the end of the script to have it run every 5 minutes.

And also send mail every 5 minutes ? That is far too frequent. Maybe you should rethink the whole idea. Anyway, to repeat tasks use [tt]cron[/tt].

The output file will pile up, so I am going to try and script it to delete the prior day mounts.

That is simple and frequent. We already have dozens of threads about deleting files older than whatever. Please search this forum's old threads.

Chris,

Try using lastfile="$( ls -1tr /rae/tmp/reportmounts.*.* | tail -1 )" to get the latest file to email.

And if this is Solaris you can use either mailx or uuencode to either mail or attach the resultant file.

As Feherke mentioned though, doing this every five minutes is a little overkill.
Adding a command to delete older verisons has been heavily documented on this site.

TIP: find, xargs, exec

Hope this helps
Alan

Hi

Oops. You are right, Alan. With -r ( --reverse ) the newest file is listed last. Thanks for the correction.
