"GOTO" in a korn shell script

Weary in West Chester — Wed, 25 Sep 2002 18:03:20 GMT

Hello Gang,

I have a ksh script that has me stumped. I have added an "if-then-else-fi" around some existing code that used to all run unconditionally, and now I've created a problem. Can it be the here file ( << endofsort) causing the problem? As always, I appreciate your help. I haven't stumped you yet:-)

This is the block of code that has the problem:

if [[ $_pass1 = "1" ]]
then
syncsort 2>> testfile << endofsort
/infile pas1800.dbasub00 fixed 240
/infile ps2001p.p27510 fixed 240
/fields f1 1 131 character
/keys f1
/outfile pas1800.dbasub00.pass1.memo fixed 240
/statistics
/end
endofsort
export RTNCODE=`echo $?`
echo Return code is $RTNCODE >> testfile
case $RTNCODE in
0) ;;
*) echo $STEP TERMINATED ABNORMALLY !!!!!!!!!! |tee -a testfile
echo Error Code $RTNCODE |tee -a testfile
exit $RTNCODE ;;
esac
#
else
cp pas1800.dbasub00 pas1800.dbasub00.pass1.memo

Hi Weary:

Make sure that your 'endofsort' begins at the leftmost character (the first) on the line.

Regards!

I don't see "fi" to close the if-then block.

Gosh James, you're the best. That's all it was. We indented to make it "pretty". Well, so much for looking good. It's working fine now. Thanks so much.

Hi (again) Weary:

/No_Points_Please/

I like pretty, rigourously indented code too, but this is one case where you have to abide by a "higher rule" :-)

Glad to have been of help.

Regards!

Although the normal '<< EOF' here-document insists that the ending token (EOF) is hard up against the left margin, the alternative form '<<- EOF' does not require this. But it will strip leading white space from your here document, which is why it works.

Example:
cat <<- EOF
hello 1
hello 2
EOF

produces
hello 1
hello 2

Martin,

Thanks for the additional info. I checked the man page (ksh - TRU64 Unix) and found that the "-" just strips off tabs from the beginning of the here document and not all white space. With tabs, it works like a champ.

Martin stated that "the alternative form '<<- EOF' does not require this. But it will strip leading white space from your here document, which is why it works. "

Keep in mind that this works WITH TABS ONLY; not spaces.
