i have URL https://my.waves.com/:r:/documents%20-/csv%20upload that loaded the screen then show edc_data.csv
above file edc_data.csv file move unix Location(/equ/str/loaded)
can you please how to write shellscripts
Assuming your URL https://my.waves.com/:r:/documents%20-/csv%20upload is correct and links to a CSV file, you can use this script:
#!/bin/sh
curl -L 'https://my.waves.com/:r:/documents%20-/csv%20upload' > /equ/str/loaded/edc_data.csv
exit 0
This will download the file edc_data.csv and put it directly in /equ/str/loaded/.

I want to add lines '{"index":{"_id":$number_of_id}}' to my file name ss.josn before each json object (which is a line)
cat ss.json
input example:
{"msisdn":"255742005249","subscription_date":"2021-05-26T16:41:40.467Z","optout_date":"2022-01-03T19:12:59.808Z","total_charged_amount":1300}
{"msisdn":"255742009077","subscription_date":"2019-12-31T22:00:00.000Z","optout_date":"2022-01-09T14:08:00.282Z","total_charged_amount":3370}
{"msisdn":"255742009703","subscription_date":"2019-12-31T22:00:00.000Z","optout_date":"2022-01-01T12:34:02.104Z","total_charged_amount":400}
Desired output:
{"index":{"_id":1}}
{"msisdn":"255742005249","subscription_date":"2021-05-26T16:41:40.467Z","optout_date":"2022-01-03T19:12:59.808Z","total_charged_amount":1300}
{"index":{"_id":2}}
{"msisdn":"255742009077","subscription_date":"2019-12-31T22:00:00.000Z","optout_date":"2022-01-09T14:08:00.282Z","total_charged_amount":3370}
{"index":{"_id":3}}
{"msisdn":"255742009703","subscription_date":"2019-12-31T22:00:00.000Z","optout_date":"2022-01-01T12:34:02.104Z","total_charged_amount":400}
If you can ensure that each line is a json struct and you don't have multiline case, a script like this should do the job:
#!/bin/bash
_id=0
while read -r line; do
echo "{"index":{"_id":$_id}}" >> result.json
echo $line >> result.json
_id=$((_id+1))
done < ss.json
Maybe not the most elegant option, but you will have a result.json file with your desired output.

I have log file for checking transactions, and I have error lines, so I need those error lines to be exported to a .csv file? is there any code using linux bash shell script can do this?
suppose your error lines consists ERROR.
then
grep "ERROR" errorfile.txt | tr -s '[:blank:]' ',' >> errorfile.csv
csv conversion is based on blank spaces to each cell.you can replace blank filter with anything

Simple question:
Is it currently possible to invoke LibreOffice from a command line to open a *.xlsx and convert/save it as a *.csv?
Alternatively, if this is not possible what is the current best method for doing this via command line (needs to be invokable via script)?
Thanks,
Here is the command:
localc --headless --convert-to csv:"Text - txt - csv (StarCalc)" *.xlsx
The above will save all converted files in current directory(directory from where you'll run the command). All converted files will have their filename extensions changed to csv.
Alternative, method is the use of unoconv which i've not used.
