Linux Script Nested if statements giving a syntax error

Question

I am trying to embed several if statements in the following:

#!/bin/bash # start_server.sh # # Use this script to start the MarketDataTransmitter. # # Usage: ./start_server.sh Starts the MarketDataTransmitter. reset=$(tput sgr0) red=$(tput setaf 1) green=$(tput setaf 2) yellow=$(tput setaf 3) cyan=$(tput setaf 6) echo directory=$(ls -l) check_exist=$(awk -va="$directory" -vb="MarketDataTransmitter" 'BEGIN { print index(a, b) }') if [ "$check_exist" = "0" ]; then # MarketDataTransmitter is not present. echo "${red}[ERROR]${reset} Could not start ${yellow}MarketDataTransmitter${reset}." echo " ${yellow}MarketDataTransmitter${reset} could not be found." else # MarketDataTransmitter is present. processes=$(ps -ef | grep -i "MarketDataTransmitter" | grep -v "grep" | grep -v "bash" | awk '{ print $8 }') check_run=$(awk -va="$processes" -vb="MarketDataTransmitter" 'BEGIN { print index(a, b) }') if [ "$check_run" = "0" ]; then # MarketDataTransmitter is not running. if [ -e "srv.log" ]; then if [ -s "srv.log" ]; then if [ -d "logs" ]; then date_time=$(date '+%Y%m%d_%H_%M_%S') new_log_name="srv_$date_time.log" mv srv.log $new_log_name mv $new_log_name logs else mkdir logs date_time=$(date '+%Y%m%d_%H_%M_%S') new_log_name="srv_$date_time.log" mv srv.log $new_log_name mv $new_log_name logs fi else echo "srv.log is empty and will be removed." rm -rf srv.log fi else # No srv.log but this is to start MarketDataTransmitter so we can ignore. fi ./MarketDataTransmitter > srv.log & echo "${yellow}MarketDataTransmitter${reset} has been started." else # MarketDataTransmitter is already running. echo "${red}[ERROR]${reset} Could not start ${yellow}MarketDataTransmitter${reset}." echo " ${yellow}MarketDataTransmitter${reset} is already running." fi fi echo 

However, this gives me syntax complaints saying:

syntax error next to unexpected fi token

on the very last "fi"

Does anyone know why?

Thanks.

You have an else and fi else with no lines between them in lines 44-46 (just a comment between them). In bash, you need to have some kind of statement in the body of this else block or lock the else lock.
