脚本Linux csh创建日志

Question

I have a process that starts every day and I'd like to create a log that says me when is completed.

I'm a newbie on Linux, I haven't programmed before, but I've tried to write this code

#!/bin/csh
set today=`date '+%Y%m%d'`
set LOG_DIR=${SL_ROOT_FOLDER}/log/cod_flow_extractor
set LOG_FILE=settlement_report_procedure
set LOG_FILE=${LOG_DIR}/${LOG_FILE}.log_$_"$today.log"
echo "$LOG_FILE"
#eval  $LOG_FILE
#exec >> $LOG_FILE 2>&1
#exec  $LOG_FILE
alias log
echo "currDate=`date +%Y%m%d.%H:%M:%S`"

When I executed it, I haven't got a log. What am I doing wrong?

You should just redirect the output of the last echo statement:

#!/bin/csh
set today=`date '+%Y%m%d'`
# $SL_ROOT_FOLDER is defined elsewhere
set LOG_DIR=${SL_ROOT_FOLDER}/log/cod_flow_extractor
set LOG_FILE=settlement_report_procedure
# notice I removed excess '_$'
set LOG_FILE=${LOG_DIR}/${LOG_FILE}."$today.log"
# let's see if its a correct path
echo "$LOG_FILE"
echo "currDate=`date +%Y%m%d.%H:%M:%S`" > $LOG_FILE
