Not sure it really has huge benefits, but I guess something like this should work:
```
#!/bin/sh
N=20
msg_len=$(git log -1 --pretty=%B | wc -c)
if [ "$msg_len" -lt "$N" ]; then
exit 125
fi
# Here you would run your actual test and report 0 (good), 1 (bad) as needed
exit 0
```
``` #!/bin/sh N=20 msg_len=$(git log -1 --pretty=%B | wc -c) if [ "$msg_len" -lt "$N" ]; then exit 125 fi # Here you would run your actual test and report 0 (good), 1 (bad) as needed exit 0 ```
