If there are no space:

TOTAL_DOCUMENTS=74195

Use this awk

echo "TOTAL_DOCUMENTS=74195" | awk -F= '{print $NF}'
74195

One way is to use grep:

$ echo "TOTAL_DOCUMENTS = 74195" | grep -o '[0-9]\+'
74195

or since you know, that it's the last field, use awk:

$ echo "TOTAL_DOCUMENTS = 74195" | awk '{print $NF}'
74195

or just use awk for the lot:

your-command -a about.afs | awk '/TOTAL_DOCUMENTS/{print $NF}'
