[SOLVED] Removing certain strings from a file. Jpeg All jpegs

Issue

I was wondering if you guy could help. I am using a Debian 9

I need to rename all jpegs in a folder, all my jpegs are like this image_E01760728_20220301122915852_TIMING.jpg to this 20220301122915.jpg (removing image_E10176072_ & _TIMING & removing last three characters . The string 20220301122915852 is a date, month, hour, min, seconds etc capture time.

So basically my timelapse system would see pictures like this; 20220301122915.jpg

Thank you in advance

Solution

Use:

for f in *jpg; do mv "$f" "$(echo "$f" |awk -F[=_] '{print $3}' |sed 's/.\{3\}$//')".jpg ; done
