I have a script to remove lower version jars files in a directory.
#!/bin/bash
#Script to remove lower version jar files.
for PREFIX in `ls *.jar|sed 's/-[0-9\.\0-9\.a-zA-Z]*\.jar//g'|uniq -d`; do
for FILE in `ls -r ${PREFIX}*|sed '1d'`; do
echo " $FILE"
rm $FILE
done
done
It has a bug.
I have below list of Duplicate jar files in a directory.
xyz-1.1.jar
xyz-1.1.1.jar
abc-1.6.jar
abc-1.3.jar
abc-xyz-pqr-1.9.6.jar
abc-xyz-pqr-1.9.2.jar
xyz-tom.jar
xyz-tom-20120423.jar
xyz-tom-20120410.jar
abc-toolkit-1.6-runtime-5.2.0.jar
abc-toolkit-1.6-runtime-5.0.0.jar
The bug is with xyz pattern jar files.
BUG:
Script is removing xyz-1.1.1.jar file instead of xyz-1.1.jar
Script is removing xyz-tom-20120423.jar and xyz-tom-20120410.jar files.

I'm trying to make a recycle bin for UNIX, so I have two scripts. 1 to delete the file and move it to the bin, the other script to restore the file back to its original location.
my restore script only works if the person gives the path to the deleted file.
ex: sh restore ~/trashbin/filename
How do I hardcode into my script so that I don't need to give the path to the deleted file it should already know to look in the trashbin for the file. My restore script works only when someone calls in the path to the file.
#!/bin/bash
rlink=$(readlink -e "$1")
rname=$(basename "$rlink")
function restoreFile() {
rlink=$(readlink -e "$1")
rname=$(basename "$rlink")
rorgpath=$(grep "$rname" ~/.restore.info | cut -d":" -f2)
rdirect=$(dirname "$rorgpath")
#echo $orgpath
if [ ! -d "$rdirect" ]
then
mkdir -p $rdirect
#echo $var
mv $rlink $rorgpath
else
mv $rlink $rorgpath
fi
}
if [ -z "$1" ]
then
echo "Error no filename provided."
exit 1
elif [ ! -f "$1" ]
then
echo "Error file does not exist."
exit 1
elif [ -f "$rorgpath" ]
then
echo "File already exists in original path."
read -p "Would you like to overwrite it? (y/n)" ovr
if [[ $ovr = y || $ovr = Y || $ovr = yes ]]
then
echo "Restoring File and overwriting."
restoreFile $1
grep -v "$rname" ~/.restore.info > ~/.restorebackup.info
mv ~/.restorebackup.info ~/.restore.info
fi
else
echo "Restoring file into original path."
restoreFile $1
grep -v "$rname" ~/.restore.info > ~/.restorebackup.info
mv ~/.restorebackup.info ~/.restore.info
fi
When you "remove" the file from the file-system to your trash-bin, move it so that its path is remembered. Example: removing file /home/user/file.txt should mean moving this file to ~/.trash/home/user/file.txt. That way, you'll be able to restore files to the original location, and you'll have auto-complete work, since you can do: sh restore ~/.trash/<TAB><TAB>
I am facing an issue, I have to delete files from some folders given in Path.lst,
The entire script is working fine but when some wrong path is given in Path.lst the script does exits out of the loop and perform no operation on the next paths.
But the last line
echo -e "\n ENDING SCRIPT SUCCESSFULLY ON `date` " >> $LOG_FILE
gets executed because exit 1 is not working in this part
if [ ! -d $path ]
then
echo -e "\nERROR :$path IS INVALID." >> $LOG_FILE
echo -e "\nENDING SCRIPT WITH ERRORS ON `date`" >> $LOG_FILE
exit 1
---------------------------------------------------------------------------------------
THE SCRIPT IS LIKE :
echo -e "\nSTARTING SCRIPT ON `date`">> $LOG_FILE
if [ $1 -gt 0 ]
then
DAYS_BFOR="$1"
else
echo -e "\nERROR :Please pass a single positive integer to the script" >>$LOG_FILE
echo -e "\nENDING SCRIPT WITH ERRORS ON `date` " >> $LOG_FILE
exit
fi
cat Path.lis | sed 's|^PATH[0-9]*=||g' | while read path
do
if [ ! -d $path ]
then
echo -e "\nERROR :$path IS INVALID." >> $LOG_FILE
echo -e "\n ENDING SCRIPT WITH ERRORS ON `date` " >> $LOG_FILE
exit 1
else
echo -e "\nFILES DELETED FROM THE "$path" DIRECTORY --" >> $LOG_FILE
find $path -type f -mtime +$DAYS_BFOR -printf "%TY-%Tm-%Td %kKB %p\n" | column -t | sed "s|"$path"||g" >> $LOG_FILE 2>&1
file_count=`find $path -type f -mtime +$DAYS_BFOR | wc -l`
if [ $file_count -ge 1 ]
then
find $path -type f -mtime +$DAYS_BFOR | xargs rm 2>>$LOG_FILE 2>&1
fi
fi
done
echo Exit Status : $?
echo -e "\n ENDING SCRIPT SUCCESSFULLY ON `date`" >> $LOG_FILE
Please help and explain the reason as well.
If you only want the "ENDING SCRIPT SUCCESSFULLY" message to appear if files were successfully deleted, not if an invalid path was given you could just move the last two echo lines up to the end of the else statement like this:
else
echo -e "\nFILES DELETED FROM THE "$path" DIRECTORY --" >> $LOG_FILE
find $path -type f -mtime +$DAYS_BFOR -printf "%TY-%Tm-%Td %kKB %p\n" | column -t | sed "s|"$path"||g" >> $LOG_FILE 2>&1
file_count=`find $path -type f -mtime +$DAYS_BFOR | wc -l`
if [ $file_count -ge 1 ]
then
find $path -type f -mtime +$DAYS_BFOR | xargs rm 2>>$LOG_FILE 2>&1
fi
echo Exit Status : $?
echo -e "\n--------------------------- ENDING SCRIPT SUCCESSFULLY ON `date` ----------------------------------" >> $LOG_FILE
fi
done
If you want to just skip to the next item in the Path.lis file then just remove the exit statement from the first loop. That way it will continue to execute the script until all the lines in the file have been read, and just show an error if the current file is not a valid path.
Normally, the ls -la command shows the files and the copy access rights, owners and access group.

How can I list only list the directories/files that I have access to?
How can I copy these directories/files to a destination directory?
Try this:
a=`find $Your_Source_Path -iname "yourFolder_whose_Files_tohide" -prune -o -type f -print`
for i in $a
do
cp $Your_source $Your_Dest_Path
done
One more answer which will copy only those files whose having copy access permission. For this first navigate to the directory whose file wanted to copy. Also inside this mention your destination path first where you wanted to copy. Try the below:-
destination_Path="/Users/Home/Desktop/test"
b=~/Desktop/copyPermission.txt
if [ ! -f $b ]
then
touch $b
fi
a=`ls -l`
e="-----w--w-"
echo "\n$a" | sed '1d' > $b
g=`pwd`
while read line
do
d=`echo "$line" | awk '{print $1}'`
if [ $e != $d ]
then
r=`echo "$line" | awk '{print $9}'`
echo "Can have copy permission $g/$r"
{
cp $g/$r "$destination_Path" && echo "copied successfully"
} || {
echo "cannot copy due to some error"
}
#else
#r=`echo "$line" | awk '{print $9}'`
#echo "Cannot have copy permission $r"
fi
done <"$b"
Consider I have a file abcde.txt which may contain one or more lines of text. I want a script that will DELETE the file if it contains single line.
Something like, if 'wc -l abscde.txt' = 1 then rm abscde.txt
My system : Solaris
Here's a simple bash script:
#!/bin/bash
LINECOUNT=`wc -l abscde.txt | cut -f1 -d' '`
if [[ $LINECOUNT == 1 ]]; then
rm -f abscde.txt
fi
delifsingleline () {
if [ $(cat $1 | wc -l) = "1" ]
then
echo "Deleting $1"
echo "rm $1"
fi
}
Lightly tested on zsh. Should work on bash as well.
This is (mostly) just a reformat of Ben's answer:
wc -l $PATH | grep '^1 ' > /dev/null && rm -f $PATH
How would you insert a copyright message at the very top of every file?
#!/bin/bash
for file in *; do
echo "Copyright" > tempfile;
cat $file >> tempfile;
mv tempfile $file;
done
Recursive solution (finds all .txt files in all subdirectories):
#!/bin/bash
for file in $(find . -type f -name \*.txt); do
echo "Copyright" > copyright-file.txt;
echo "" >> copyright-file.txt;
cat $file >> copyright-file.txt;
mv copyright-file.txt $file;
done
Use caution; if spaces exist in file names you might get unexpected behaviour.
sed
echo "Copyright" > tempfile
sed -i.bak "1i $(<tempfile)" file*
Or shell
#!/bin/bash
shopt -s nullglob
for file in *; do
if [ -f "$file" ];then
echo "Copyright" > tempfile
cat "$file" >> tempfile;
mv tempfile "$file";
fi
done
to do it recursive, if you have bash 4.0
#!/bin/bash
shopt -s nullglob
shopt -s globstar
for file in /path/**
do
if [ -f "$file" ];then
echo "Copyright" > tempfile
cat "$file" >> tempfile;
mv tempfile "$file";
fi
done
or using find
find /path -type f | while read -r file
do
echo "Copyright" > tempfile
cat "$file" >> tempfile;
mv tempfile "$file";
done
You may use this simple script
#!/bin/bash
# Usage: script.sh file
cat copyright.tpl $1 > tmp
mv $1 $1.tmp # optional
mv tmp $1
File list may be managed via find utility
Working in Mac OSX:
#!/usr/bin/env bash
for f in `find . -iname "*.ts"`; do # just for *.ts files
echo -e "/*\n * My Company \n *\n * Copyright © 2018 MyCompany. All rights reserved.\n *\n *\n */" > tmpfile
cat $f >> tmpfile
mv tmpfile $f
done
