I want to rewrite a line in a conf file. The text that should be put on line 88 is: auth 0.0.0.0/0 - -
My command is :
sed -i '88s/.*/auth 0.0.0.0/0 - -/' /etc/opt/ss5/ss5.conf
But I'm getting an error
sed: -e expression #1, char 21: number option to `s' command may not be zero
How can I solve this issue ?
It is because the text you try to inject contains / which is used by sed as a separator.
You need either to escape this slash , or to use a different sed separator. Sed can accept any character as separator, i.e #.
sed -i '88s/.*/auth 0.0.0.0\/0 - -/' /etc/opt/ss5/ss5.conf
#OR
sed -i '88s#.*#auth 0.0.0.0/0 - -#' /etc/opt/ss5/ss5.conf

Following is the xml file in which STORAGE_ACCOUNT_KEY should be replaced with EoKpaH0W/kqTv9awgIpQX5s+qQwGzXUSxMxhRjfSWG7SIUTWhut1OYQkNxhb3/9UKGf+g4tc3UaC0zKMTSrTNg==
<property>
<name>fs.azure.account.key.storageaccountname.blob.core.windows.net</name>
<value>STORAGE_ACCOUNT_KEY</value>
</property>
I have tried the following. But nothing helps me solve it.
Using / after s and before g
sed -i "s/STORAGE_ACCOUNT_KEY/EoKpaH0W/kqTv9awgIpQX5s+qQwGzXUSxMxhRjfSWG7SIUTWhut1OYQkNxhb3/9UKGf+g4tc3UaC0zKMTSrTNg==/g" test.xml
Error:-
sed: -e expression #1, char 32: unknown option to `s'
Using | after s and before g
sed -i "s|STORAGE_ACCOUNT_KEY/EoKpaH0W/kqTv9awgIpQX5s+qQwGzXUSxMxhRjfSWG7SIUTWhut1OYQkNxhb3/9UKGf+g4tc3UaC0zKMTSrTNg==|g" test.xml
Error:-
sed: -e expression #1, char 112: unterminated `s' command
Note:- $STORAGE_ACCOUNT_KEY is a dynamic variable as below
sed -i "s|STORAGE_ACCOUNT_KEY/$STORAGE_ACCOUNT_KEY|g"
To replace XML, I would adivse to use an XML parser (for example xmllint) instead of sed.
That said, your sed expression is wrong.
sed s command uses 3 delimiters (any printable character you want), but these 3 must be the same and is defined by the one right after the s command.
s/foo/bar/g # right
s|foo|bar|g # right
s|foo/bar|g # wrong
Since you replace a string with a base64 string, you should not use any of the base64 character, so don't use / as a sed delimiter in that case.
Your expression should be like this:
sed -i "s|STORAGE_ACCOUNT_KEY|EoKpaH0W/kqTv9awgIpQX5s+qQwGzXUSxMxhRjfSWG7SIUTWhut1OYQkNxhb3/9UKGf+g4tc3UaC0zKMTSrTNg==|g" test.xml
Note that the g modifier at the end of the command might not be necessary if you only have 1 string to replace per line.
How to replace folder path using following command,
sed -i "s/# pidfile: '/var/run/jboss-eap/jboss-eap.pid /# pidfile: '/var/run/jboss-eap/jboss-eap-aa.pid' /g" ks
Error: sed: -e expression #1, char 20: unknown option to `s'
When I use sed -i "s/sample/hi/g" sam.txt It working fine , but above mentioned expression throws unknown exception. How to resolve this error ? have any idea ?
You need to change the delimiter (/) in your statement, as it is also in your pattern.
sed -i "s## pidfile: '/var/run/jboss-eap/jboss-eap.pid ## pidfile: '/var/run/jboss-eap/jboss-eap-aa.pid' #g" ks
Here I replaced it wiht #, but you can use any delimiter, as long as it's not part of the pattern text.
I tried using the following sed command to replace a line in the file that I am reading .
sed -i "/$line/c\\${linerep}" "$1"
where $i is the input file where the lines are to be replaced.
I get the following error when I run the script:
sed: -e expression #1, char 65: unknown command: `0'
sed: -e expression #1, char 69: unknown command: `0'
Please tell me what changes should i make in the sed command?
Is there any other way apart from sed to do the same operation?
I am using shell script. My requirement is to find and replace the string. The string contains "/" char as well. I am getting error sed: -e expression #1, char 18: unterminated `s' command. Can someone tell how should i replace the string which has "/"?
#!/bin/bash
...
search_string="../conf/TestSystem/Inst1.xml"
rep="Inst1/Instrument.xml"
sed -i 's|${line}|${rep}/g' MasterConfiguration.xml
I tried using another sed command but that one also gave error sed: -e expression #1, char 13: unknown option to `s'
sed -e "s/${line}/${rep}/g" MasterConfiguration.xml > tempfile
Whenever you deal with shell-variables you have to get them out of the "sed-string":
For example:
sed -e "s/"${line}"/"${rep}"/g" MasterConfiguration.xml > tempfile
Otherwise sed will treat the chars as-is and search for ${line} literally:
As you see, nothing happens here.
Furthermore, if your variables contain / you need to use another delimiter for sed. I tend to use ~ in such a case, but you're free to use other chars - just be consequent and don't mix them like in your first example-sed-command:
sed 's~'${line}'~'${rep}'/g' //WRONG
sed 's~'${line}'~'${rep}'~g' //RIGHT
Combine both and it will work:
You can try this sed,
sed -i "s#${line}#${rep}#g" MasterConfiguration.xml
Problem:
Instead you have,
sed -i "s|${line}|${rep}/g" MasterConfiguration.xml
It should be,
sed -i "s|${line}|${rep}|g" MasterConfiguration.xml
Syntax:
sed "s|pattern|replacement|g"
I have a problem replacing default password hash in config file:
sed -i 's/default_password_crypted: "[^"]*"/default_password_crypted: "\$1\$mF86/UHC\$WvcIcXred6crBz2onWxyac."/' input.txt
i get following error:
sed: -e expression #1, char 74: unknown option to `s'
works:
search pattern: default_password_crypted: "$1$mF86/UHC$WvcIcX2t6crBz2onWxyac."
sed -i 's/default_password_crypted: "[^"]*"/default_password_crypted: "1234567890"/' input.txt
how do i need to write replace pattern for hash ?
thx
You need to escape the literal / inside your replacement as it’s the delimiter:
sed -i 's/default_password_crypted: "[^"]*"/default_password_crypted: "\$1\$mF86\/UHC\$WvcIcXred6crBz2onWxyac."/' input.txt
Or simply use a different character, for example a ,:
sed -i 's,default_password_crypted: "[^"]*",default_password_crypted: "\$1\$mF86,UHC\$WvcIcXred6crBz2onWxyac.",' input.txt
You also don’t need to escape the $ inside the replacement.
