In the process of writing the'ecf' file, use the keyword% to retrieve the pre-defined variables. However, there are many functions in the shell syntax that also need to use %. Can the two methods coexist? How to do it

The shell example is as follows
```
s2=${s1% *}
echo $s2
```

The error log is as follows:

: Mismatched ecfmicro(%) count(1)  at :   s2=${s1% *}

thanks

Hi,

Check out the docs: https://confluence.ecmwf.int/display/ECFLOW/ecFlow++variables - I think this answers your question: "if there are two %-characters together they are concatenated to form a single %-character in the job-file. For example, if you need to execute the UNIX date command "date +%d". For a job, you must enter it as "date +%%d" into the ecFlow file."

Cheers, Iain
