Need help on below requirement.
I have a file with list of URLs and need to mask query param values as shown in below example in Linux.
http://hostname:port/uri?data=value&data1=value2&data3=value3
to
http://hostname:port/uri?data=XXX&data1=XXX&data3=XXX
thanks
you could replace any character that is not a &, it is more efficient than enumerating all possible ranges:
$ echo 'http://hostname:port/uri?data=value&data1=va%20lue2&data3=value3' | \
sed -r 's/=[^&]+/=XXX/g'
http://hostname:port/uri?data=XXX&data1=XXX&data3=XXX

I have a SED Command in a code and I need to understand what its actually doing ?
Below is what I see in code ?
show partitions {curr_table}' | sed 's/[\t]/,/g' > /tuber/dag_run_ctx/tbl_qc.csv;
Any idea what would the above Sed command do?
Replace or substitute each occurrence of <TAB> character represented as \t with , character.
And save the output into file: /tuber/dag_run_ctx/tbl_qc.csv

I have this file name:
ABCD1B02.C50.N1995009.2019353.dat
I would like to extract the final 7 numbers and put space like this
extr=2019 353;
In bash script:
fname='ABCD1B02.C50.N1995009.2019353.dat'
extr="${fname:${#fname}-11:4} ${fname:${#fname}-7:3}"

Provided that this sting is dynamic. If it is as Domain_1234_20180821230101.dat then I want 1234_20180821. How can I do that?
I.e., when Domain_12_20180821230101.dat then I want output as 12_20180821
A primitive solution that works for the examples you gave would be:
grep -oP '[0-9]+_[0-9]{8}' <<< "$string"
This will extract any substring consisting of a variable-length number, followed by an underscore, followed by an 8-digit number if present, else return nothing.
You can find more infos to help you understand this command and adjust it to your requirements if necessary under grep --help and https://www.regular-expressions.info/tutorial.html.

I have this text:
111.11.1.111(*)222.22.2.221(mgn)333.33.3.333(srv)
111.11.1.111(*)333.33.3.333(srv)222.22.2.222(mgn)
222.22.2.223(mgn)111.11.1.111(*)333.33.3.333(srv)
I only want to know the IP's before (mgn), output:
222.22.2.221
222.22.2.222
222.22.2.223
thanks
Through grep,
$ grep -oP '(?:\d{1,3}\.){3}\d{1,3}(?=\(mgn\))' file
222.22.2.221
222.22.2.222
222.22.2.223
Through sed,
$ sed 's/.*\b\(\([0-9]\{1,3\}\.\)\{3\}[0-9]\{1,3\}\)(mgn).*/\1/g' file
222.22.2.221
222.22.2.222
222.22.2.223

I want to search for a number in string that does not occur between numbers.
For example:
string="10003096,10007051,10003098,10007053,10000952,10002696,10003619,900004608"
If i search for 10003096, then it exists.
But if i search for 1000, then it means it does not exist.
Even if i search for 10000952,10002696, then it means it does not exist.
How can i write the shell script for this?
Please help.
I have tried various options with grep and sed but it does not help.
Pad both your 'needle' and 'haystack' with commas. E.g.
echo ",$string," | grep ",10007053,"
