UNIX for Dummies Questions & Answers

All -

I have a situation where I have some hardcoded directories in a file. I want to be able to search for string that I know will always be the same in each environment and then replace that entire line with the new environment specific information. I am using the sed command to do this, but I've encountered some issues.

Here is part of the script I am running:

ENV_UPPER=`echo $TWO_TASK | tr '[a-z]' '[A-Z]'`
echo "The environment in UPPER CASE IS $ENV_UPPER"

ENV_LOWER=`echo $TWO_TASK | tr '[A-Z]' '[a-z]'`
echo "The environment in lower case IS $ENV_LOWER"

OLD_STRING1=`grep 'location.href' $FILE_NAME`
echo "The first string to be replaced is: $OLD_STRING1"
NEW_STRING1=" location.href = \"/pls/$ENV_LOWER/OracleNavigate.Responsibility\";"
echo "The string will be replaced by : $NEW_STRING1"

echo "Create files with the current instance name"
cat $FILE_NAME | sed "s/$OLD_STRING1/$NEW_STRING1/g" > slc_inv_upload.jsp

echo "Successfully Completed..."

By running this, I am getting the following error:

This job executing for file slc_req_upload.jsp
The updated directory will be testno1
The environment in UPPER CASE IS OFD2
The environment in lower case IS ofd2
The first string to be replaced is: location.href = "/pls/adfasgaoft2/OracleNavigate.Responsibility";
The string will be replaced by : location.href = "/pls/ofd2/OracleNavigate.Responsibility";
Create files with the current instance name
sed: Function s/ location.href = "/pls/adfasgaoft2/OracleNavigate.Responsibility";/ location.href = "/pls/ofd2/OracleNavigate.Responsibility";/g cannot be parsed.
Successfully Completed...

Does anyone have any thoughts on how I could resolve this?

Thanks,

Thanks for doing some footwork here. I lot of people would just say "I'm getting 'cannot be parsed' from sed...how to fix that?"

When you do:
cat $FILE_NAME | sed "s/$OLD_STRING1/$NEW_STRING1/g" > slc_inv_upload.jsp

the problem is that your variables contain your delimiters. So switch your delimiters.

sed "s/$a/$b/"
sed "s!$a!$b!"
sed "s=$a=$b='
sed s%$a%$b%'

are equally valid to sed. In fact you can use any chacter at all. But you need to pick one that's not in the data. Also some characters are special to the shell. I'm not sure which shell you're using, but with ksh and your data, ! might be a good delimiter for you.

You may have trouble with those backslashes. sed will eat them. But that may be what you want.

You can also prefix each 'forward slash' with a 'back slash'. I have to say though that Perderabo's solution is much more elegant. Here's the changes to the script:

NEW_STRING1=" location.href = \"\/pls\/$ENV_LOWER\/OracleNavigate.Responsibility\";"
