As per code it is getting matched. not sure why it assigning to cols=0.

Any inputs please.

Input : passed is

 
shell.sh c tablename.
 

 
if [$1=c]; then
cols=1
table=$2
else
cols=0
table=$1
fi

Output:

 
[interactive mode output:
 
+ [c=c]
dcs.sh[3]: [c=c]:  not found
+ cols=0
+ table=c
2

[ and ] need spaces around them to be parsed as individual commands.
