+Progress indicator |
|
|
|
+------------------ |
|
|
|
+ |
|
|
|
+The below sfeed_update wrapper script counts the amount of feeds in a sfeedrc |
|
|
|
+config. It then calls sfeed_update and pipes the output lines to a function |
|
|
|
+that counts the current progress. It writes the total progress to stderr. |
|
|
|
+Alternative: pv -l -s totallines |

|

|
+ # Pass lines as input to stdin and write progress status to stderr. |
|
|
|
+ # progress(totallines) |
|
|
|
+ progress() { |
|

|
+ total="$(($1 + 0))" # must be a number, no divide by zero. |
|
|
