How effectlively to call a bash function to another in a program-CodePudding

I have below Bash script where I am trying to Create functions for creating colors for output text in the script, I am trying to call these function into another one but somehow its not working.

I looked around and googled, but didn't get the anything concrete to my situation, Can someone please help we to get, what i am doing wrong?

Script:

#!/bin/bash
read -rsp $'Please Enter password below: ' SSHPASS
echo -n  ""
export SSHPASS

RED=$'\033[0;31m'; GREEN=$'\033[32m'; YELLOW=$'\033[1;33m'; BLUE=$'\033[0;34m'; ENDCOLOR=$'\033[0m'
#
function warning() {
  printf "${RED}[WARNING] %s${ENDCOLOR}\n" "$1" >&2
}

function information() {
  printf "${YELLOW}[INFO] %s${ENDCOLOR}\n" "$1"
}

function ok() {
  printf "${GREEN}[INFO] %s${ENDCOLOR}\n" "$1"
}

function hostclr() {
  printf "${BLUE}[INFO] %s${ENDCOLOR}\n" "$1"
}

function remote_connect() {
   target_host=$1

   sshpass -e ssh -q "${target_host}"  "true" -o StrictHostKeyChecking=no -o ConnectTimeout=60 2>>/dev/null
   if [[ $? -eq 0 ]]

   then
     SMBconf=$(sshpass -e ssh -q -t "$target_host" "grep -i vfs /etc/samba/smb.conf")

     if [[ $SMBconf == "" ]];then
         printf "%-20s s %5s 0s\n" hostclr "$target_host"  ok "NO VFS Stack found(not Vulnerable!)"

     elif [[ $SMBconf != "" ]];then
         printf "%-20s s %5s 0s\n"  hostclr "$target_host"  warning "Its Vulnerable!"

     else
         printf "%-20s s  %5s 0s\n" hostclr "$target_host" "Unable to get the ssh connection"
     fi
fi
}  2>/dev/null
export -f remote_connect
< samba_new_Servers xargs -P10 -n1 -d'\n' bash -c 'remote_connect "$@"' --
unset SSHPASS

Result:

Edit:

I am using functions hostclr, ok etc

CodePudding user response：

export -f remote_connect

You exported only one function. You have to export all that you use.

export RED GREEN YELLOW etc...
export -f remote_connect hostclr ok information etc...

CodePudding user response：

You still have to use command substitution to get the output of ok et al. to use as an argument to printf.

printf "%-20s s %5s 0s\n" "$(hostclr "$target_host")"  "$(ok "NO VFS Stack found(not Vulnerable!)")"
