Couldn't navigate through directories using bash script

  • 772

Through script I am not able to change into directories and list the files. cd is not working.

Here is my script

#!/bin/bash

export HOME=/home/yesh

DIR_START=2
DIR_END=`wc -l < ${HOME}/conf/DirectoryList`

while [ ${DIR_START} -le ${DIR_END} ];
do
        DIR1=`cat /home/yesh/conf/DirectoryList | sed -ne ${DIR_START}p`
        echo "cd ${HOME}/${DIR1}"
        find . -type f > /home/yesh/Files_"$(date +%Y%d%m)".log
done



DirectoryList
/home/yesh/yesh.txt
/home/yesh/Yesh
/home/yesh/BACKUP
/home/yesh/venv3
/home/yesh/pythonfund

The above are the list of directories I need to navigate through in ${HOME}/conf/DirectoryList

bash bashrc bash-history

    If the list of directories is not too large, I'd suggest avoiding the shell loop altogether and simply passing the list to find via an array:

    mapfile -t dirs < "${HOME}/conf/DirectoryList"
find "${dirs[@]}" -type f > /home/yesh/Files_"$(date +%Y%d%m)".log

    If you still want to use a shell loop instead, then

    while read -r dir; do
  find "$dir" -type f
done < "${HOME}/conf/DirectoryList" > /home/yesh/Files_"$(date +%Y%d%m)".log

    If the intent of your cd was to remove the leading path components from the output, then you can do that within find by replacing the default print by an explicit -printf '%P\n'
