If I execute some command in a Linux shell, how can I store the output into a string (variable) so I can use it later? I need this for a Bash script, please help.

To save the str output as a string in R, we can use capture. output function along with str function. It would be better if we save it in an object as str_df<- capture. output(str(df)) so that it can be recalled in the future in current session.
the shortcut is Ctrl + Shift + S ; it allows the output to be saved as a text file, or as HTML including colors!
To store the output of a command in a variable, you can use the shell command substitution feature in the forms below: variable_name=$(command) variable_name=$(command [option ...] arg1 arg2 ...) OR variable_name='command' variable_name='command [option ...]
str=$(command)
result=`command` or result=$(command) both assign the output of command to the result variable.
