I have many csv files that should be displayed each one in many graphs :
data1.csv
data2.csv
data3.csv
data4.csv
data5.csv
.
.
.
dataN.csv
I am using a script to display only one chart for one file :
./script.sh data1.csv
How to generate graphs for all files at once ?
Call your script inside a loop
for file in $file_list; do
./script.sh $file
done
or, if you want all plots in one file then put this loop inside plot script (gnuplot 4.4+)
plot for [i=1:N] 'data'.i.'.csv' . . .
EDIT: If you want to pass filenames through command line args, wrap it in another script like this
#!/bin/bash
for file in "$#"; do
[ -f $file ] && ./script.sh $file
done

I am writing a little script that outputs a list of duplicate files in the directory, ie. pairs of XXX.jpg and XXX (1).jpg. I want to use the output of this script as an argument to a command, namely ql (quicklook) so I can look through all such images (to verify they are indeed duplicate images, or just filenames). For instance, I can do `ql (' which will allow me to look through all the files 'XXX (1).jpg'; but I want to include in that list also the original 'XXX.jpg' files.
Here is my script so far:
dups=()
for file in *\(*; do
dups+=( "${file}" )
breakdown=( $file )
dupfile="${breakdown[0]}.jpg"
if [ -e "$dupfile" ]; then
dups+=( "$dupfile" )
fi
done
echo ${dups[#]}
As far as building an array of the required filenames goes, it works. But when it comes to invoking something like ql $(./printdups.sh), the command gets confused by the filenames with spaces. It will attempt to open 'XXX' as a file, and then '(1).jpg' as another file. So the question is, how can I echo this array such that filenames with spaces are recognised as such by the command I pass it to?
I have tried changing line 3 to:
dups+=( "'$file'" )
And:
dups+=( "${file/ /\ }" )
Both to no avail.
You can't pass arrays from one process to another. All you are doing is writing a space-separated sequence of file names to standard output, and the unquoted command substitution in ql $(./printdups.sh) fails for the same reason you need an array in the first place: word-splitting does not distinguish between spaces in file names and spaces between file names.
I would recommend defining a function, rather than a script, and have that function populate a global array that you can access directly after the function has been called.
get_dups () {
dups=()
for file in *\(*; do
dups+=( "$file" )
read -a breakdown <<< "$file" # safer way to split the name into parts
dupfile="${breakdown[0]}.jpg"
if [ -e "$dupfile" ]; then
dups+=( "$dupfile" )
fi
done
}
get_dups
ql "${dups[#]}"
I have a lot of csv files that I want to classify according to their filename in different folders.
If the file *lefto.csv save them in a folder called lefto
If the file *righto.csv save it in a folder called right
If the file *sagital.csv save it in a folder called sagittal
If the file does not obey any previous condition, save the file in a folder called animals
So far I have been using the mv command, but I would like to make a loop
bash solution:
for f in *.csv; do
if [[ "$f" =~ .*(lefto|righto|sagital).csv ]]; then
mv "$f" "${BASH_REMATCH[1]}"
else
mv "$f" "animals"
fi
done
So I have written a bash script (named music.sh) for a Raspberry Pi to perform the following functions:
When executed, look into one single directory (Music folder) and select a random folder to look into. (Note: none of these folders here have subdirectories)
Once a folder within "Music" has been selected, then play all mp3 files IN ORDER until the last mp3 file has been reached
At this point, the script would go back to the folders in the "Music" directory and select another random folder
Then it would again play all mp3 files in that folder in order
Loop indefinitely until input from user
I have this code which does all of the above EXCEPT for the following items:
I would like to NOT play any other "album" that has been played before
Once all albums played once, then shutdown the system
Here is my code so far that is working (WITH duplicates allowed):
#!/bin/bash
folderarray=($(ls -d /home/alphekka/Music/*/))
for i in "${folderarray[#]}";
do
folderitems=(${folderarray[RANDOM % ${#folderarray[#]}]})
for j in "${folderitems[#]}";
do
echo `ls $j`
cvlc --play-and-exit "${j[#]}"
done
done
exit 0
Please note that there isn't a single folder or file that has a space in the name. If there is a space, then I face some issues with this code working.
Anyways, I'm getting close, but I'm not quite there with the entire functionality I'm looking for. Any help would be greatly appreciated! Thank you kindly! :)
Use an associative array as a set. Note that this will work for all valid folder and file names.
#!/bin/bash
declare -A folderarray
# Each folder name is a key mapped to an empty string
for d in /home/alphekka/Music/*/; do
folderarray["$d"]=
done
while [[ "${!folderarray[*]}" ]]; do
# Get a list of the remaining folder names
foldernames=( "${!folderarray[#]}" )
# Pick a folder at random
folder=${foldernames[RANDOM%${#foldernames[#]}]}
# Remove the folder from the set
# Must use single quotes; see below
unset folderarray['$folder']
for j in "$folder"/*; do
cvlc --play-and-exit "$j"
done
done
Dealing with keys that contain spaces (and possibly other special characters) is tricky. The quotes shown in the call to unset above are not syntactic quotes in the usual sense. They do not prevent $folder from being expanded, but they do appear to be used by unset itself to quote the resulting string.
Here's another solution: randomize the list of directories first, save the result in an array and then play (my script just prints) the files from each element of the array
MUSIC=/home/alphekka/Music
OLDIFS=$IFS
IFS=$'\n'
folderarray=($(ls -d $MUSIC/*/|while read line; do echo $RANDOM $line; done| sort -n | cut -f2- -d' '))
for folder in ${folderarray[*]};
do
printf "Folder: %s\n" $folder
fileArray=($(find $folder -type f))
for j in ${fileArray[#]};
do
printf "play %s\n" $j
done
done
For the random shuffling I used this answer.
One liner solution with mpv, rl (randomlines), xargs, find:
find /home/alphekka/Music/ -maxdepth 1 -type d -print0 | rl -d \0 | xargs -0 -l1 mpv
I have a capture file in a directory in which some logs are being written in a file
word.cap
now there is a script in which when its size becomes exactly 1.6Gb then it clears itself and prepares files in below format in same directory-
word.cap.COB2T_1389889231
word.cap.COB2T_1389958275
word.cap.COB2T_1390035286
word.cap.COB2T_1390132825
word.cap.COB2T_1390213719
Now i want to pick all these files in a script one by one and want to perform some actions.
my script is-
today=`date +%d_%m_%y`
grep -E '^IPaddress|^Node' /var/rawcap/word.cap.COB2T* | awk '{print $3}' >> snmp$today.txt
sort -u snmp$today.txt > snmp_final_$today.txt
so, what should i write to pick all file names of above mentioned format one by one as i will place this script in crontab,but i don't want to read main word.cap file as that is being edited.
As per your comment:
Thanks, this is working but i have a small issue in this. There are
some files which are bzipped i.e. word.cap.COB2T_1390213719.bz2, so i
dont want these files in list, so what should be done?
You could add a condition inside the loop:
for file in word.cap.COB2T*; do
if [[ "$file" != *.bz2 ]]; then
# Do something here
echo ${file};
fi
done
I have few files in a folder with name pattern in which one of the section is variable.
file1.abc.12.xyz
file2.abc.14.xyz
file3.abc.98.xyz
So the third section (numeric) in above three file names changes everyday.
Now, I have a script which does some tasks on the file data. However, before doing the work, I want to check whether the file exists or not and then do the task:
if(file exist) then
//do this
fi
I wrote the below code using wildcard '*' in numeric section:
export mydir=/myprog/mydata
if[find $mydir/file1.abc.*.xyz]; then
# my tasks here
fi
However, it is not working and giving below error:
[find: not found [No such file or directory]
Using -f instead of find does not work as well:
if[-f $mydir/file1.abc.*.xyz]; then
# my tasks here
fi
What am I doing wrong here ? I am using korn shell.
Thanks for reading!
for i in file1.abc.*.xyz ; do
# use $i here ...
done
I was not using spaces before the unix keywords...
For e.g. "if[-f" should actually be " if [ -f" with spaces before and after the bracket.
