replacing a line of unknown charecters in a file

malavm · #1 (**permalink**) 07-25-2007

Hi All

I have a requirement where using a script I grep a file for string (KSG/Password in below ) , get the next line which is the password and I need replace the whole line of unknown special charecters (encrypted password) with another line as given below .

As in below i need to get the line , assign it to a variable
STRNG="<value>#!OE/+puLDjXm/Yg4W34vHvV6rdiGx0plE</value>" then replace

$STRNG with "<value>psoft123</value>"

The file i grep contains as below

<value>
</NameValuePair>
<NameValuePairPassword>
<name>KSG/Password</name>
<value>#!OE/+puLDjXm/Yg4W34vLvV6rdiGx0plE</value>
</NameValuePairPassword>
<NameValuePair>
<name>KSG/DB_User</name>
<value>vass</value>
</NameValuePair>

when I use 'sed' as below , I get the error "sed:command garbled"

sed 's/'$STRNG'/'<value>psoft123</value>'/' abc.xml > abc1.xml

+ sed s/ <value>#!OE/+puLDjXm/Yg4W34vHvV6rdiGx0plE</value>/<value>psoft123</value>/ abc.xml
+ 1> abc1.xml
sed: command garbled: s/

Can some one please help me with this

Thanks

Code:

sed '/KSG\/Password/{n;s#<value>.*</value>#<value>psoft123</value>;}' abc.xml

Hi

Thanks for the reply but I am still getting the error

bash-2.05$ sed '/KSG\/Password/{n;s#<value>.*</value>#<value>psoft123</value>;}' abc.xml
sed: command garbled: /KSG\/Password/{n;s#<value>.*</value>#<value>psoft123</value>;}

if you are open to alternative, here's a Python script:

Code:

#!/usr/bin/python
data=open("file").readlines()
data=[i.strip() for i in data]
for num,line in enumerate(data):
    if "KSG/Password" in line:
        data[num+1] = "<value>psoft123</value>"

for i in data:
 print i

output:

Code:

 # ./test.py #or use > to redirect to new file
<value>
</NameValuePair>
<NameValuePairPassword>
<name>KSG/Password</name>
<value>psoft123</value>
</NameValuePairPassword>
<NameValuePair>
<name>KSG/DB_User</name>
<value>vass</value>
</NameValuePair>

sorry - my bad:

Code:

sed '/KSG\/Password/{n;s#<value>.*</value>#<value>psoft123</value>#;}' abc.xml

Code:

awk '{ if ( match($0, "KSG/Password") ) { getline; print "<value>psoft123<\/value>" } else { print } }' filename
