I want a script that is able to read the content of a text file which contains folder names and moves the folders from their directory to a specific folder. Here is my script:
#!/bin/bash
for i in $(cat /folder/collected/folders.txt)
do
mv /fromfilelocation/$i /folder/Collected/
done
This script is partly working as it copies only the last folder in the text file, as for the other folders it gives the error "not possible: data or directory not found" But the folder is there and according to the error the folder directory is correctly displayed.
What should I do in order to make it work correctly ??
You can use this:
#!/bin/bash
for sample in `awk '{print $1}' All_bins.txt`
do mv "$sample" All_Good_Bins
done
Use while loop instead
while read i; do
mv fromfilelocation/"$i" /folder/Collected/
done </folder/collected/folders.txt

I'm working on looping through files in bash script and for the most part it is working but the directory name is echoed twice. How could I change the code to only echo the files in the directory and not the directory itself.
This is my code:
Directory=C:/temp/
find $Directory
for filename in "$Directory"/;
do
echo $filename
done
This is what I see in my terminal:
C:/temp/
C:/temp/QJ07312433_10_19_2021_snapshot.xml
C:/temp/QJ07312433_10_28_2021_snapshot.xml
C:/temp/
The find command prints all the names in the hierarchy headed by $Directory. Then you loop through the single string $Directory/, and echo that. This is why you get the second echo of the directory name.
If you want the loop to process the find output in the loop, you need to pipe to it:
find "$Directory" | while read -r name; do
echo "$name"
done
I need to move each *.lis file in its current directory to a new directory and add to the file's existing filename for an application to pickup the file with the new name.
For example:
Move /u01/vista/vmfiles/CompressGens.lis and /u01/vista/vmfiles/DeleteOnline.lis
to
/u01/vista/Migration_Logs/LIS.BHM.P.MIGRATION_LOGS.FBA."$(date '+%m%d%y%H%M%S')"CompressGens.lis
and
/u01/vista/Migration_Logs/LIS.BHM.P.MIGRATION_LOGS.FBA."$(date '+%m%d%y%H%M%S')"DeleteOnline.lis
What I started out with in my script:
cp -f /u01/vista/vmfiles/*.lis /u01/vista/Migration_Logs/LIS.BHM.P.MIGRATION_LOGS.FBA."$(date '+%m%d%y%H%M%S')"*.lis
There are multiple *.lis in the /u01/vista/vmfiles/ directory, and depending on the system and day, the *.lis files will not always be the same. Sometimes it is "DeleteOnline.lis" and CompressGens.lis but not ArchiveGens.lis. Then the next day will be CompressGens.lis and ArchiveGens.lis.
So I will need to get the *.lis filenames in the /u01/vista/vmfiles/ directory, and then move each one.
You need a loop, so that you can do one file at a time.
ls -1tr *.lis | while read File
do
cp -p $File ../Migration_Logs/${File%.lis}.$(date '+%m%d%y%H%M%S').CompressGens.lis &&
mv $File ../Migration_Logs/${File%.lis}.$(date '+%m%d%y%H%M%S').DeleteOnline.lis
done
${File%.lis} is the bash/korn means of stripping that suffix - see ksh or bash man page.
The "&&" idiom is in order only to mv the file to the 2nd archived name if the copy for the 1st archived file works.
#Abe Crabtree, Thanks for the help in pointing me in the right direction. Below is the final code that worked.
ls -1tr *.lis | while read File
do
mv $File /u01/vista/Migration_Logs/LIS.BHM.P.MIGRATION_LOGS.FBA.$(date '+%m%d%y%H%M%S').${File%.lis}.lis
done
I need help copying content from various files to others (same name and format, different path).
For example, $HOME/initial/baby.desktop has text which I need to write into $HOME/scripts/baby.desktop. This is very simple for a single file, but I have 2500 files in $HOME/initial/ and the same number in $HOME/scripts/ with corresponding names (same names and format). I want append (copy) the content of file in path A to path B (which have the same name and format), to the end of file in path B without erase the content of file in path B.
Example content of $HOME/initial/*.desktop to final $HOME/scripts/*.desktop. I tried the following, but it don't work:
cd $HOME/initial/
for i in $( ls *.desktop ); do egrep "Icon" $i >> $HOME/scripts/$i; done
Firstly, I would backup $HOME/initial and $HOME/scripts, because there is lots of scope for people misunderstanding your question. Like this:
cd $HOME
tar -cvf initial.tar initial
tar -cvf scripts.tar scripts
That will put all the files in $HOME/initial into a single tarfile called initial.tar and all the files in $HOME/scripts into a single tarfile called scripts.tar.
Now for your question... in general, if you want to put the contents of FileB onto the end of FileA, the command is
cat FileB >> FileA
Note the DOUBLE ">>" which means "append" rather than single ">" which means overwrite.
So, I think you want to do this:
cd $HOME/initial/baby.desktop
cat SomeFile >> $HOME/scripts/baby.desktop/SomeFile
where SomeFile is the name of any file you choose to test with. I would test that has worked and then, if you are happy with that, go ahead and run the same command inside a loop:
cd $HOME/initial/baby.desktop
for SOURCE in *
do
DESTINATION="$HOME/scripts/baby.desktop/$SOURCE"
echo Appending "$SOURCE" to "$DESTINATION"
#cat "$SOURCE" >> "$DESTINATION"
done
When the output looks correct, remove the "#" at the start of the penultimate line and run it again.
I solved it, if some people want learn how to resolve is very simple:
using Sed
I need only the match (or pattern) line "Icon=/usr/share/some_picture.png into $HOME/initial/example.desktop to other with same name and format $HOME/scripts/example.desktop, but I had a lot of .desktop files (2500 files)
cd $HOME/initial
STRING_LINE=`grep -l -R "Icon=" *.desktop`
for i in $STRING_LINE; do sed -ne '/Icon=/ p' $i >> $HOME/scripts/$i ; done
_________
If you need only copy all to other file with same name and format
using cat
cd $HOME/initial
STRING_LINE=`grep -l -R "Icon=" *.desktop`
for i in $STRING_LINE; do cat $i >> $HOME/scripts/$i ; done
I am having trouble with several bits of code, I am no expert in Linux Bash programming unfortunately so I have tried unsuccessfully to find something that works for my task all day and was hoping you could help guide me in the right direction.
I have many large files that I would like to split according to the third field within each of them, I would like to keep the header in each of the sub-files, and save the created sub-files in new directories created from the root names of the files.
The initial files stored in the original directory are:
Downloads/directory1/Levels_CHG_Lab_S_sample1.txt
Downloads/directory1/Levels_CHG_Lab_S_sample2.txt
Downloads/directory1/Levels_CHG_Lab_S_sample3.txt
and so on..
Each of these files have 200 columns, and column 3 contains values from 1 through 10.
I would like to split each of the files above based on the value of this column, and store the subfiles in subfolders, so for example sub-folder "Downloads/directory1/sample1" will contain 10 files (with the header line) derived by splitting the file Downloads/directory1/Levels_CHG_Lab_S_sample1.txt.
I have tried now many different steps for these steps, with no success.. I must be making this more complicated than it is since the code I have tried looks aweful…
Here is the code I am trying to work from:
FILES=Downloads/directory1/
for f in $FILES
do
# Create folder with root name by stripping file names
fname=${echo $f | sed 's/.txt//;s/Levels_CHG_Lab_S_//'}
echo "Creating sub-directory [$fname]"
mkdir "$fname"
# Save the header
awk 'NR==1{print $0}' $f > header
# Split each file by third column
echo "Splitting file $f"
awk 'NR>1 {print $0 > $3".txt" }' $f
# Move newly created files in sub directory
mv {1..10}.txt $fname # I have no idea how to do specify the files just created
# Loop through the sub-files to attach header row:
for subfile in $fname
do
cat header $subfile >> tmp_file
mv -f tmp_file $subfile
done
done
All these steps seem very complicated to me, I would very much appreciate if you could help me solve this in the right way. Thank you very much for your help.

You have a few problems with your code right now. First of all, at no point do you list the contents of your downloads directory. You are simply setting the FILES variable to a string that is the path to that directory. You would need something like:
FILES=$(ls Downloads/directory1/*.txt)
You also never cd to the Downloads/directory1 folder, so your mkdir would create directories in cwd; probably not what you want.
If you know that the numbers in column 3 always range from 1 to 10, I would just pre-populate those files with the header line before you split the file.
Try this code to do what you want (untested):
BASEDIR=Downloads/directory1/
FILES=$(ls ${BASEDIR}/*.txt)
for f in $FILES; do
# Create folder with root name by stripping file names
dirname=$(echo $f | sed 's/.txt//;s/Levels_CHG_Lab_S_//')
dirname="${BASENAME}/${dirname}/"
echo "Creating sub-directory [$dirname]"
mkdir "$dirname"
# Save the header to each file
HEADER_LINE=$(head -n1 $f)
for i in {1..10}; do
echo ${HEADER_LINE} > ${dirname}/${i}.txt
done
# Split each file by third column
echo "Splitting file $f"
awk -v dirname=${dirname} 'NR>1 {filename=dirname$3".txt"; print $0 >> filename }' $f
done
I want to write a script that do specific thing:
I have a txt file e.g.
from1/from2/from3/apple.file;/to1/to2/to3;some not important stuff
from1/from2/banana.file;/to1/to5;some not important stuff
from1/from10/plum.file;/to1//to5/to100;some not important stuff
Now i want to copy file from each line (e.g. apple.file), from original directory tree to new, non existing directories, after first semicolon (;).
I try few code examples from similar questions, but nothing works fine and I'm too weak in bash scripting, to find errors.
Please help :)
need to add some conditions:
file not only need to be copy, but also rename. Example line in file.txt:
from1/from2/from3/apple.file;to1/to2/to3/juice.file;some1
from1/from2/banana.file;to1/to5/fresh.file;something different from above
so apple.file need to be copy and rename to juice.file and put in to1/to2/to3/juice.file
I think thaht cp will also rename file but
mkdir -p "$to"
from answer below will create full folder path with juice.file as folder
In addidtion after second semicolon in each line will be something different, so how to cut it off?
Thanks for all help
EDIT: There will be no spaces in input txt file.
Try this code..
cat file | while IFS=';' read from to some_not_important_stuff
do
to=${to:1} # strip off leading space
mkdir -p "$to" # create parent for 'to' if not existing yet
cp -i "$from" "$to" # option -i to get a warning when it would overwrite something
done
Using awk
(run the awk command first and confirm the output is fine, then add |sh to do the copy)
awk -F";" '{printf "cp %s %s\n",$1,$2}' file |sh
Using shell (get updated that need manually create folder, base on alfe's
while IFS=';' read from to X
do
mkdir -p $to
cp $from $to
done < file
I had this same problem and used tar to solve it! Posted here:
tmpfile=/tmp/myfile.tar
files="/some/folder/file1.txt /some/other/folder/file2.txt"
targetfolder=/home/you/somefolder
tar --file="$tmpfile" "$files"
tar --extract --file="$tmpfile" --directory="$targetfolder"
In this case, tar will automatically create all (sub)folders for you! Best,
Nabi
