Help with test statement
Hello,
I am trying to build a test statement but I can't make it work
I want to rearrange some fields, so if my "$cfg" variable contains a string ending with .log (*.log) I want to move it in another field.
Any help will be much appreciated!
Thank you

Shell:sh
Code:
if [ "$cfg" = log ]
then
log="${cfg}"
cfg=""
fi

Just need help with this statement:
Code:
if [ "$cfg" = log ]

According to my notes:
True if cfg contains log

Is that right ?

HTML Code:
echo $cfg | grep ".log$" >/dev/null 2>&1

flag=`echo $?`

if [ $flag -eq 0 ]; then
     echo "$cfg ends with .log"
     #perform your operations
else
     #other operations of setting to null/or as required.
fi

You may do like this:
1st extract the extension of file, store in a variable and use that in if condition
Code:
.....
....
ext=$(echo $cfg | sed 's/.*\(...\)$/\1/')
if [ "$ext" = "log" ]
.....
....

Complete script:

Code:
#!/usr/bin/sh
old_IFS=$IFS
IFS=$' '
echo MINUTES\;HOURS\;DAY_OF_MONTH\;MONTH\;DAY_OF_WEEK\;SCRIPT\;CFG\;P1\;P2\;LOG
cat cron.txt | sed '/^$/d' | sed '/^#/d'| sed 's/>//g' | sed 's/ (. ~\/.profile ; timex / /g'| sed 's/)/ /g' | sed 's/ 2&1//g' | sed 's/*/+/g' | tr -s ' ' | sed
 's/ / /g' | while read mins hours day_of_mon month day_of_week script cfg p1 p2 log
do
if [ "$log" = "" ]
then
log="${p2}"
p2=""
fi
if [ "$log" = "" ]
then
log="${p1}"
p1=""
fi
if [ "$cfg" = log ]
then
log="${cfg}"
cfg=""
fi
 
echo ${mins}\;${hours}\;${day_of_mon}\;${month}\;${day_of_week}\;${script}\;${cfg}\;${p1}\;${p2}\;${log}
done
IFS=$old_IFS
exit

Sample from cron.txt
Code:
30 04  *  *  * (. ~/.profile ; timex /Data/bin/load_data.sh /Data/bin/1.cfg ) 2>&1
32 04  *  *  * (. ~/.profile ; timex /Data/bin/load_data.sh /Data/bin/2.cfg ) 2>&1
00 05  *  *  * (. ~/.profile ; timex /Data/bin/load_data.sh /Data/bin/3.cfg ) >> /Data/logs/load_data.log 2>&1

..
if [ "$log" = "" ]
then
log="${p1}"
p1=""
fi
ext=$(echo $cfg | sed 's/.*\(...\)$/\1/')
if [ "$ext" = "log" ]
then
log="${cfg}"
cfg=""
fi

echo ${mins}\;${hours}\;${day_of_mon}\;${month}\;${day_of_week}\;${script}\;${cfg}\;${p1}\;${p2}\;${log}
..
