[SOLVED] FILENAME.sh: line NUMBER: VARIABLE: not found

This is driving me insane. I think it has to do with Synology

This is being ran on a Synology Server.

Code:

### VARIABLES ###
LOGIF=/volume7/homes/admin/scripts/data/achclean-logi.txt
HOWOLD=$(cat $LOGIF | wc -l)
# END DEFINITIONS


if (( ${HOWOLD} >= 7 )); then
  echo -e "WORKS" >> 
fi

I get this error in the terminal: scriptname: line Number: [Value of HOWOLD]: not found
If I run this on Linux, RedHat, it works.

Code:

HOWOLD=$(cat dfile | wc -l)

if (( ${HOWOLD} >= 2 )); then
   echo "WORKS"
fi

EDIT:
NO LUCK!!!!!!!!

Code:

if [ "$HOWOLD" >= "7" ]; then # if 7, then it's been 7 days!

sh: 7: unknown operand

NO LUCK!!!!!!!!

Code:

if (( "$HOWOLD" >= "7" )); then # if 7, then it's been 7 days!

scriptname: line Number: [Value of HOWOLD]: not found

I don't think "HOWOLD=$(cat $LOGIF | wc -l)" will work in sh. You need to run it in bash.

I dont have bash. But it seems to work since I am using it in other scripts on this synology.

I'm thinking it's because whatever version of Shell this Synology is using is older then I am use to.

I got it working by using -ge inplace of >=

if [ ${HOWOLD} -ge 7 ];

I love shell scripting, but man it can be painful at times

Within square brackets [[ ]], the operators differ for strings vs numerics http://www.tldp.org/LDP/abs/html/comparison-ops.html

In future, it would probably help if you tell us exactly what shell you are running so we may assist better.

Thanks. Looks like the Synology is using Ash "/bin/ash"

I'll keep that in mind for the future
