I have an XML file containing a path which is different depending of my environments. I created a $ENV_PATH variable which contain the correct string. How can I parse and replace $ENV_PATH in my XML file by the value of the environment variable?
Assuming you're running on linux, you can use the sed command to do exactly what you're asking. If you have the following XML file in my_file.xml:
<example>
<my_tag>SUBSTITUTE_ME</my_tag>
</example>
You can use the following command:
sed -i 's/SUBSTITUTE_ME/$ENV_PATH/g' my_file.xml
This will result in the following file (if ENV_PATH=/dev)
<example>
<my_tag>/dev</my_tag>
</example>

We have a file which has unformatted xml content in a single line
<sample:text>Report</sample:text><sample:user name="11111111" guid="163g673"/><sample:user name="22222222" guid="aknen1763y82bjkj18"/><sample:user name="33333333" guid="q3k4nn5k2nk53n6"/><sample:user name="44444444" guid="34bkj3b5kjbkq"/><sample:user name="55555555" guid="k4n5k34nlk6n711kjnk5253"/><sample:user name="66666666" guid="1n4k14nknl1n4lb1"/>
If we find a particular string suppose "22222222", i want to remove the entire string that surrounds the matched string. In our case the entire portion around 22222222 i.e., <sample:user name="22222222" guid="aknen1763y82bjkj18"/> should be removed and the file has to be saved.
How can we do it? Please help
You can do it using sed utility by invoking it like this:
sed -i file -e 's/<[^<]*"22222222"[^>]*>//'
I have a property file(env.properties) that contains below property name and value:
oracle.install.option=UPGRADE_DB
I have another shell script (test.sh) that runs source command and try to access the value of property oracle.install.option :
#!/bin/sh
source env.properties
echo "value is...... " $oracle.install.option
When I run the file .test.sh, I am unable to get the value of above property. Output:
env.properties: line 1: oracle.install.option=UPGRADE_DB: command not found
value is ......... .install.option
My expected output is UPGRADE_DB. Kindly assist me in getting this resolved.
This properties file is not a shell file, and dots are not allowed in environment variable names (read here)
So your hack could have worked if the properties had no dot in them, but not here.
So if you want to display it in your shell, you have another good alternative: parse the properties file using awk
awk -F= '{if ($1=="oracle.install.option") print "value is......",$2}' env.properties
Quick Summary: I need to create a Bash script to change the text within a node automatically every week. The script will match the node and replace the text inside them (if this is possible)? How would I do this?
Long Summary:
I host a Minecraft server which has shops, each of which have their own .xml file in the /ShowcaseStandalone/ffs-storage/ directory. Every Sunday my server restarts and executes several commands into the terminal to reset several things. One thing that I am trying to make change is one of the shops. I am wanting to change the text in the node <itemstack> and the text in the node <price>. I am simply wanting to take text from a .txt file in a different folder, and insert it into that node. The problem is, that the text in the node will change every week. Is there any way to replace a specific line or text within two nodes using bash?

You can use xmlstarlet to edit a XML file in a shell like this :
xmlstarlet edit -L -u "/scs-shop/price[#type='double']" -v '99.66' file.xml
NOTE
"/scs-shop/price[#type='double']" is a Xpath expression
see xmlstarlet ed --help
The XML way is cool, but if you need to use normal bash tools, you can modify a line using sed. For instance:
PRICE=123
sed -i "s/\(<price.*>\)[^<>]*\(<\/price.*\)/\1$PRICE\2/" $XML_FILE_TO_MODIFY
This will replace the price with 123.
That sed command seems daunting, so let me break it down:
\(<price.*>\)[^<>]*\(<\/price.*\) is the pattern to match. \( ... \) are parenthesis for grouping. <price.*> matches the opening price tag. [^<>]* matches anything except angle brackets, and in this case will match the contents of the price tag. <\/price.* matches the end of the price tag. Forward slash is a delimiter in sed, so I escape it with a back slash.
\1$PRICE\2 is the text to replace the matched text with. \1 refers to the first matched parenthesis group, which is the opening price tag. $PRICE is the variable with the desired price in it. \2 refers to the second parenthesis group, in this case the closing tag.
I did not have the luxury of having xmlstarlet.
I found a solution though simply by doing an inline replacement;
template-parameter.xml
<ns:Parameter>
<ns:Name required="true">##-ParamName-##</ns:Name>
<ns:Value>
<ns:Text>##-ParamValue-##</ns:Text>
</ns:Value>
</ns:Parameter>
Snippet
tokenName="foo"
tokenValue="bar"
#Replace placeholders in parameter template element
myParamElement=$(cat template-parameter.xml)
myParamElement=${myParamElement//##-ParamName-##/$tokenName}
myParamElement=${myParamElement//##-ParamValue-##/$tokenValue}
Result
<ns:Parameter>
<ns:Name required="true">foo</ns:Name>
<ns:Value>
<ns:Text>bar</ns:Text>
</ns:Value>
</ns:Parameter>
I have a non.txt file and want to write a shell script to remove a string from the entire file. File has the following data :-
24321,247,654,"^A","91350","JEFFR2",21714,,1,243,654,"^A","91350","JEFFR2",21714,,1,654,0,"P","N","1140828","CA",,,,,"06037","C016","14","7",0,"21714 JEFFERS LN","","SANTA CLARITA","CA","913503917","","","","20140828"
And from the above set of data i want to remove "^A".
Please help me to find out the solution.
Try this:
sed -i 's/"^A"//g' non.txt
I have a parameter file(parameter.txt) which contain like below:
SASH=/home/ec2-user/installers
installer=/home/hadoop/path1
And My shell script(temp_pull.sh) is like below:
EPATH=`cat $1|grep 'SASH' -w| cut -d'=' -f2`
echo $EPATH
${EPATH}/data-integration/kitchen.sh -file="$KJBPATH/hadoop/temp/maxtem/temp_pull.kjb"
When I run my temp_pull.sh like below:
./temp_pull.sh parameter.txt
$EPATH gives me correct path, but 3rd line of code takes only partial path.
Error code pasted below:
/home/ec2-user/installers-->out put of 2nd line
/data-integration/kitchen.sh: No such file or directory**2-user/installer** -->out put of 3rd line
There is no need to manually parse the values of the file, because it already contains data in the format variables are defined: var=value.
Hence, if the file is safe enough, you can source the file so that SASH value will be available just by saying $SASH.
Then, you can use the following:
source "$1" # source the file given as first parameter
"$SASH"/data-integration/kitchen.sh -file="$KJBPATH/hadoop/temp/maxtem/temp_pull.kjb"
The problem is file which we were using was copied from windows to UNIX.So delimiter issue are the root cause.
By using dos2unix paramfile.txt we are able to fix the isue.
command:
dos2unix paramfile.txt
This will convert all the delemeter of windows to unix format.
