Inserting a line at the end

Shazin · July 28, 2009, 3:51am

Hi All,

I am using the below script to enter the URL at the end of file:

echo "Enter the URL that should point to the particular microsite"
read url
sed "$a $url" redirects.virgin-atlantic.com.conf > temp

But am getting the below error:

./script.sh[6]: [0: not found
Unrecognized command: Redirect permanent /kpmgxy system-unavailable

Please can you advise.

Best Regards,
Shazin

What is $a here? I am bit confused with your requirement.

If you just want to read and append a line to the end of a file, then try this.

 
echo "Enter the URL that should point to the particular microsite"
read url
echo $url >>filename

It's because $a is interpreted by the shell. You could use

sed '$a '$url redirects.virgin-atlantic.com.conf > temp

or much simpler

echo $url >> redirects.virgin-atlantic.com.conf

Hi,

Still getting the below error:

Enter the URL that should point to the particular microsite
Redirect permanent /kpmgxy system-unavailable
./script.sh[6]: [0: not found
sed: command garbled: $a Redirect
Redirects Setup

Hi,

There's something I don't understand.
is
redirects.virgin-atlantic.com.confthe name of the file? In this case, what is the use of
> temp?

Another question : this script is written for csh shell or ksh. How can I convert this for bash shell? All the Tuto i find use different syntaxes and don't works for bash shell...

If you have little time to explain me or a link to a good website, it'll be really appreciable.

Thanks

Are you sure you want to use "sed"?
Because, the syntax is wrong?

Or are you trying to use "cat"?
As per your requirement you must be using cat.

Hi

I am using the below script to enter a line in the file:

#!/bin/ksh
# To delete the last line if it contains the pattern Redirect permanent / http://www.virgin-atlantic.com
echo "Enter the URL that should point to the particular microsite"
read url
# To delete the last line if it contains the pattern Redirect permanent / http://www.virgin-atlantic.com
grep "Redirect permanent / http://www.virgin-atlantic.com" redirects.virgin-atlantic.com.conf > output1
if [$? -eq 0] ; then
   rm -r output1
   sed '$d' redirects.virgin-atlantic.com.conf > temp
   #cp temp redirects.virgin-atlantic.com.conf
   echo $url >> temp
   echo "Redirect permanent / http://www.virgin-atlantic.com" >> temp
   echo "Redirects Setup"
else
   echo $url >> temp
   echo "Redirects Setup"
fi

and am getting the error below:

Enter the URL that should point to the particular microsite
Redirect permanent /kpmgxy Virgin Atlantic Airways - Popup
./script.sh[7]: [0: not found
Redirects Setup

Please can you advise.

If you'd have posted the whole part before, not just the part where you thought the error was, we could have told you that the testing expression for the if requires whitespace surrounding the brackets, eg

if [ $? -eq 0 ]; then
