script problem in reading parm file

Chun Boon Lee — Tue, 25 Jan 2005 04:33:12 GMT

portion of the script:

#!/bin/sh
. test.ini
cp $param_file2 $param_file_bak2

cat $param_file2 > a.log
echo "----below is the reading value ------" >> a.log
for i in `cat $param_file2`
do
echo $i
echo $i >> a.log
done > tparam_file

Output:
[PD_ODS.s_m_FHOPEHS_TO_ODS_OTHERS_ALL_22]
[PD_ODS.s_m_FHOPEHS_TO_ODS_OTHERS_ALL_2]
[PD_ODS.s_m_FHOPEHS_TO_ODS_OTHERS_ALL_11]
[PD_ODS.s_m_FHOPEHS_TO_ODS_OTHERS_ALL_AA]
[PD_ODS.s_m_FHOPEHS_TO_ODS_OTHERS_ALL_A]
[PD_ODS.s_m_FHOPEHS_TO_ODS_OTHERS_ALL_A1]

----below is the reading value ------
[PD_ODS.s_m_FHOPEHS_TO_ODS_OTHERS_ALL_22]
[PD_ODS.s_m_FHOPEHS_TO_ODS_OTHERS_ALL_2]
1
[PD_ODS.s_m_FHOPEHS_TO_ODS_OTHERS_ALL_AA]
[PD_ODS.s_m_FHOPEHS_TO_ODS_OTHERS_ALL_A]
1

We found out that there is a file name "1" in the same directory as the script.

Any idea how to over come this?

thanks

Hi,
can first check that the filenames are ok with:
ls -b PD_ODS.s_m_FHOPEHS_TO_ODS_OTHERS_ALL_*
This should eliminate any filename corruption.
Secondly why do you have a "> tparam_file"
at the end of your loop?

Hi,

try to use while loop instead of for

syntax:
cat $param_file2 | while read
do
i=$REPLY
echo $i
echo $i >> a.log
done

If I remove the file 1, the output is ok. If I touch a file A, then the the output become:
PD_ODS.s_m_FHOPEHS_TO_ODS_OTHERS_ALL_22]
[PD_ODS.s_m_FHOPEHS_TO_ODS_OTHERS_ALL_2]
1
A
A
1

somehow there cannot have a file with a letter or number same as the end of output in the same directory as the script.

This script is a portion of the application script.

What is in test_ini ?

Re: script problem in reading parm file

Chun Boon Lee — Tue, 25 Jan 2005 05:11:01 GMT

test.ini content

param_file2="p.txt"
param_file_bak2="p.bak"

Hi,
I would assume that the problem is that the shell performs file name substitution in the current directory. The cure is to qoute the regular expressions in the script.
You say that it is a portion of the script; typical places to look for culprits are square brackets, e.g. [a-z] and asterisks.
Try double qouting.

regards,
John K.

Change your script to ...

#!/bin/sh
. test.ini
cp $param_file2 $param_file_bak2

cat $param_file2 > a.log
echo "----below is the reading value ------" >> a.log
set -f
for i in `cat $param_file2`
do
echo $i
echo $i >> a.log
done > tparam_file
set +f

Thanks very much, I had solved the problem using the set -f and set +f
