I'm trying to write a script to find all of the files with .production in names, decrypt those files and save copies of them without .production.
Example files:
./functions/key.production.json
./src/config.production.js
Here is my code:
decrypt() {
echo $1
for file in $(find . -name "*.$1.*")
do
echo "some $file"
openssl enc -aes-128-cbc -a -d -salt -pass pass:asdffdsa -in $file -out $(sed -e "p;s/.$1//")
done
}
$(sed -e "p;s/.$1//") is the part that hangs. You can check that out by adding set -x and executing your script. This is because sed expectes an input file/stream, and there is none given to it.
You could rather use bash substring replacement "${file//.$1}"
${string//$substring_to_remove/}
All occurrences of the content after // is replaced in the main string, with the content after the last /
So, the working function would be
decrypt() {
echo $1
for file in $(find . -name "*.$1.*")
do
echo "some $file"
openssl enc -aes-128-cbc -a -d -salt -pass pass:asdffdsa -in $file -out "${file//.$1}"
done
}
You can avoid the subshell $(find . -name ".$1.") by using a while loop.
decrypt() {
echo "$1"
local file
while read -r file; do
echo "some $file"
PROCESS-YOUR-FILE-AND-DO-YOUR-STUFF_HERE
done < <(find . -name "*.$1.*")
}

what I am trying to achieve is, to delete same filenames(filename+modfiedtimestamp)exisitng in Src_Dir1 and Src_Dir2
So first i have tried to deploy all the filenames to tempa(Src_Dir1) and tempb(Src_Dir2) respectively.
Below is the screenshot of the source directory.
Files inside archive be like this and few files outside too..
So, initially I am want to deal with the files inside Archive(SRC_Dir1) and later outside Archive(SRC_Dir2) what I am trying to do is to use a while loop to read each and every filename and string concat with the modified timestamp(mtime) and input to tempc(like for example it should be like AirTimeActs_2018-12-03.csv+2019-01-24 14:41:53.000000000 -0500 = AirTimeActs_2018-12-03.csv_2019-01-24 14:41:53.000000000 -0500 this is how it should be generating into tempc file for each and every filename inside Archive(SRC_Dir1). This is where I am stuck under string concat variable section on how to proceed. Please help me with the code, hope I am comprehensible.
IMPORTANT
(Really appreciate it, if you help me out with the extension of the code which i haven't mentioned here and yet to achieve which is - >
Have to implement the same code(which I am trying to do for tempa, I'd like to do it for tempb too and name it as tempd) and then do a file data compare between tempc and tempd) if there is any kind of same data filename, then delete the file existing in Src_Dir2, if there is no same data filename, then do nothing.)

I want to make my script password protected. If I use this code it works:
ACTUAL="sam123"
read -s -p "Password: " enteredpass
I also want to protect the script from being read with cat and vi. I tried to use vim -x <script> to encrypt it but then it won't allow me to run it.
I am using a generic user and haven't gotten anywhere.
You can't do this securely without your sysadmin's help, but you can do something sorta-kinda-maybe-not-really-adequate without it.
So, let's say you create your script like so:
cat >myscript <<EOF
echo "Doing something super secret here"
EOF
...but you don't want anyone who doesn't know the password to run it, even if they're using a shared account. You can do this by encrypting it:
gpg -ac <myscript >myscript.asc
...and then embedding that plaintext into a script:
#!/usr/bin/env bash
{ gpg -d | bash -s "$#"; } <<'EOF'

-----END PGP MESSAGE-----
EOF
That said, other users in the shared account can still collect your password if they connect to and trace your process while it's running -- running strace on the copy of bash -s will show the text being fed into its stdin. In general, you shouldn't rely on shared accounts for anything that needs to remain confidential.
Late answer for posterity, how about using openssl? here's my scriptencrypt.sh
It generates a new .sh file that requires a password
#!/bin/bash
if [ -z "$1" ]; then echo "usage: $(basename $0) script"; exit 1; fi
script=$(cat "$1")
checksum="$(echo "$script" | md5sum | awk '{ print $1 }')"
extension=$([[ "$(basename $1)" =~ .\.. ]] && echo ".${1##*.}" || echo "")
cat << EOF > "${1%.*}.enc${extension}"
#!/bin/bash
read -r -d '' encrypted_script << EOF2
$(openssl aes-256-cbc -a -salt -in /dev/stdin -out /dev/stdout <<< "${script}")
EOF2
read -s -p "Enter script password: " password
echo
unencrypted_script=\$(openssl aes-256-cbc -d -a -salt -in /dev/stdin -out /dev/stdout <<< "\${encrypted_script}" -pass pass:"\${password}" 2>/dev/null | tr -d '\000')
clear
checksum="\$(echo "\$unencrypted_script" | md5sum | awk '{ print \$1 }')"
if [ "\${checksum}" = "${checksum}" ]; then
eval "\${unencrypted_script}"
exit 0
else
echo "Wrong password inserted"
exit 1
fi
EOF
I'm writing a script that should do a dictionary attack on a text file passed as argument encrypted with openssl.
Here is what I wrote:
#!/bin/bash
# written by Cosimo Colaci
passwords=( $(cat italian.txt) ) # italian.txt is a list of words
for word in ${passwords[#]}
do
openssl enc -d -aes-128-cfb1 -in "$1" -k $word 2>/tmp/err
pid=$$
wait $pid
if [ -s /tmp/err ]
then
continue
else
openssl enc -d -aes-128-cfb1 -in "$1" -k $word;
break;
fi
done
I also tried
for word in ${passwords[#]}
do
openssl enc -d -aes-128-cfb1 -in "$1" -k $word &>/dev/null
exitstatus=$?
if [ $exitstatus -ne 0 ]
then
continue
else
openssl enc -d -aes-128-cfb1 -in "$1" -k $word;
break;
fi
done
The problem is that on some cicles the exit status is 0 even if decription fails, as I can see by launching:
bash -x ./crack_italian.sh filetodecript.txt
but the same command, in a terminal, behave as expected and fails.
while read -r word; do
if openssl enc -d -aes-128-cfb1 -in "$1" -k "$word" >openssl.out 2>&1
then
cat openssl.out
break
fi
done <italian.txt
rm -f openssl.out
You don't need to read the file into an array.
You can use the exit status directly in an if statement. Note that in your second example, the assignment of $? to exitstatus changes $?.
Variable expansions should be double quoted.
Slightly shorter:
while read -r word; do
openssl enc -d -aes-128-cfb1 -in "$1" -k "$word" >openssl.out 2>&1 &&
{ cat openssl.out; break; }
done <italian.txt
rm -f openssl.out
I am having trouble looping and searching. It seems that the loop is not waiting for the find to finish. What am I doing wrong?
I made a loop the reads a file line by line. I then want to use that "name" to search a directory looking to see if a folder has that name. If it exists copy it to a drive.
#!/bin/bash
DIRFIND="$2"
DIRCOPY="$3"
if [ -d $DIRFIND ]; then
while IFS='' read -r line || [[ -n "$line" ]]; do
echo "$line"
FILE=`find "$DIRFIND" -type d -name "$line"`
if [ -n "$FILE" ]; then
echo "Found $FILE"
cp -a "$FILE" "$DIRCOPY"
else
echo "$line not found."
fi
done < "$1"
else
echo "No such file or directory"
fi
Have you tried xargs...
Proposed Solution
cat filenamelist | xargs -n1 -I {} find . -type d -name {} -print | xargs -n1 -I {} mv {} .
what the above does is pipe a list of filenames into find (one at a time), when found find prints the name and passes to xarg which moves the file...
Expansion
file = yogo
yogo -> | xargs -n1 -I yogo find . -type d -name yogo -print | xargs -n1 -I {} mv ./<path>/yogo .
I hope the above helps, note that xargs has the advantage that you do not run out of command line buffer.
I created script to compare files in folder (with the name .jpg and without it BUT with the same NAME).The problem that script searches for files in ONE directory ,not in SubDirectories!How i can fix it?
for f in *
do
for n in *.jpg
do
tempfile="${n##*/}"
echo "Processing"
echo "${tempfile%.*}"
echo "$f"
if [[ "${tempfile%.*}" = $f ]]
then
echo "This files have the same name!"
//do something here
else
echo "No files"
fi
done
done
This requires bash version 4 for associative arrays.
shopt -s globstar nullglob extglob
declare -A jpgs
for jpg in **/*.jpg; do
name=$(basename "${jpg%.jpg}")
jpgs["$name"]=$jpg
done
for f in **/!(*.jpg); do
name=$(basename "$f")
if [[ -n ${jpgs["$name"]} ]]; then
echo "$f has the same name as ${jpgs["$name"]}"
fi
done
You can also try using find
find . -type f -name "*.sh" -printf "%f\n" | cut -f1 -d '.' > jpg.txt
while read line
do
find . -name "$line.*" -print
done < jpg.txt
