sed edit in place -i issues
Hello,

I am attempting to create a command that I can eventually put into a loop so I can edit 1file on many servers. I would like to edit the file in place with sed -i. If not I will take any suggestions on how to use a temp file. I need to remove a email address from the configuration file below.


O/S=rhel4
Shell=bash

File Location:
Code:
filename1=/var/log/swatch/.swatchrc.apache

Original File:
Code:
[root@radio1 swatch]# cat .swatchrc.apache 
watchfor /File size limit exceeded/
throttle 10:00,key=$7
mail=arup.error@intertechmedia.com logswatch@intertechmedia.com, subject=Apache Error File size limit occured

Desired File:
Code:
[root@radio1 swatch]# cat .swatchrc.apache 
watchfor /File size limit exceeded/
throttle 10:00,key=$7
mail=logswatch@intertechmedia.com, subject=Apache Error File size limit occured

My Attempt:
Code:
[root@radio1 swatch]# cat .swatchrc.apache | sed  's/arup.error@intertechmedia.com //'g
watchfor /File size limit exceeded/
throttle 10:00,key=$7
mail=logswatch@intertechmedia.com, subject=Apache Error File size limit occured
[root@radio1 swatch]#

My attempt works, however when I try with the -i flag in sed I get the following:
Code:
[root@radio1 swatch]# cat .swatchrc.messages | sed -i 's/arup.error@intertechmedia.com //'g
sed: can't read -: No such file or directory
[root@radio1 swatch]#

I think the issue may be related to the configuration file having a . in front.

Regards,
abacus

You are! Smilie

Try this but make a backup first of the original file:

Code:
sed 's/arup.error@intertechmedia.com //g' .swatchrc.apache > tempfile && mv tempfile .swatchrc.apache

Thanks fo your time.

Upon executing It appeared that it would work. I was asked to overwrite file. However no dice. Still has the email address that I wanted to remove. Also is there a way to place a yes in there. So I will not get asked again? There will be many files to edit.

Code:
[root@radio5 bin]# sed 's/arup@intertechmedia.com //g' /var/log/swatch/.swatchrc.apache > tempfile && mv tempfile /var/log/swatch/.swatchrc.apache 
mv: overwrite `/var/log/swatch/.swatchrc.apache'? y
[root@radio5 bin]# cd /var/log/swatch/                 
[root@radio5 swatch]# cat .swatchrc.apache 
watchfor /File size limit exceeded/
throttle 10:00,key=$7
mail=arup.error@intertechmedia.com logswatch@intertechmedia.com, subject=Apache Error File size limit occured

I am reading man pages now, as well as searching google.

It works fine for me with the given sample file.
Do you get the desired output on the screen if you don't redirect it to a file?

To disable the prompt before overwriting of the the mv command, use the -f option.

Operator Error,

As in my fault. Everything is working perfect. Thanks for your time in this matter.
