Shell Script for checking existence of a directory -

if[-d /abmusr06/abm/users/dywrk01/run_time];         echo "pack installation failed"      exit(1) fi 

this above code fine?

assuming bourne shell (/bin/sh):

if [ -d /abmusr06/abm/users/dywrk01/run_time ]     echo "pack installation failed"     exit 1 fi 

• put spaces around brackets: if [ -d. think of [ (key)word - needs stand itself. wouldn't ls-l, ls(space)-l.
• use exit 1, not exit(1).
• the semicolons unnecessary if on separate lines.
• the above seems work in cygwin me.
