UNIX for Dummies Questions & Answers

You are dead right on this. there is no point repeating the same codes in many files, this will sometime takes the system down to it's knee. well , I was also planning for that paramatrized script, but , since I still new to shell arena. I did bit learn bit of shell scripting and able to create some sort of script, that does the purpose in our envoiornment. You people are great help, during the creation of script. I am workiing hard to learn it, I know this is no rocket science. however, I still have some question from my existing script. I would appriciate, if you could elaborate on following lines.
does this time format looks ok to you?

Code:

typeset -i mHHMM=`date +%H%M`
typeset -i mDD=$(date +%d)
mDay=`date +%a`
if [[ "${mDay}" = "Sun" && ${mHHMM} -gt 0150 ]]; then

Do you no longer want that line you were asking about modified, then? I still don't have enough information to give you an answer about it.

Code:

typeset -i mHHMM=`date +%H%M`

You don't need to "typeset -i", all this does is force it to evaluate a number earlier.

Numbers with leading zeroes will be interpreted as octal. This could have unforseen effects in your math. Things with digits above 7 won't work at all:

Code:

$ typeset -i val=0159
-bash: typeset: 0159: value too great for base (error token is "0159")

So you should get the strings and strip off the leading zeroes before trying to compare them; or just compare them as strings. How to do this depends on your shell and system, what is it?

Thanks Corona for this. You've always been a great help for me. I think, I need to take away the leading "zeros" from my script. thanks a lot, once again

Sorry for not getting back to this.

Still need an answer to this: As for removing leading zeroes, I still need an answer to this: But if you have BASH or a recent KSH, you can do:

Code:

while [ "${STR:0:1}" = "0" ] ; do STR="${STR:1}" ; done
