I am using jqTree in our project
http://mbraak.github.io/jqTree/
I have tree structure like this
-A
-B
-C
-C1
-C2
-D
I want to add new child E to A in 2nd position like this
-A
-B
-E
-C
-C1
-C2
-D
How can I do this???
You can use the addNodeAfter function.

I am trying to write a shell script that reads a file line by line and executes a command with its arguments taken from the space-delimited fields of each line.
To be more precise, I need to download a file from an URL which is given in the second column to the path given in the first column using wget. But I don't know how to load this file and get the values in script.
File.txt
file-18.log https://example.com/temp/file-1.log
file-19.log https://example.com/temp/file-2.log
file-20.log https://example.com/temp/file-3.log
file-21.log https://example.com/temp/file-4.log
file-22.log https://example.com/temp/file-5.log
file-23.pdf https://example.com/temp/file-6.pdf
Desired output is
wget url[1] -o url[0]
wget https://example.com/temp/file-1.log -o file-18.log
wget https://example.com/temp/file-2.log -o file-19.log
...
...
wget https://example.com/temp/file-6.pdf -o file-23.pdf
Use read and a while loop in bash to iterate over the file line-by-line and call wget on each iteration:
while read -r NAME URL; do wget "$URL" -o "$NAME"; done < File.txt
Turning a file into arguments to a command is a job for xargs:
xargs -a File.txt -L1 wget -o
xargs -a File.txt: Extract arguments from the File.txt file.
-L1: Pass all arguments from 1 line to the command.
wget -o Pass arguments to the wget command.
You can count, using a for loop and the output of seq like so:
In bash, you can add numbers using $((C+3)).
This will get you:
COUNT=6
OFFSET=18
for C in `seq "$((COUNT-1))"`; do
wget https://example.com/temp/file-${C}.log -o file-$((C+OFFSET-1)).log
done
wget https://example.com/temp/file-${COUNT}.pdf -o file-$((COUNT+OFFSET-1)).pdf
Edit: Sorry, I misread your question. So if you have a file with the file mappings, you can use awk to get the URL and the FILE and then do the download:
cat File.txt | while read L; do
URL="$(echo "${L}" | awk '{print $1}'"
FILE="$(echo "${L}" | awk '{print $2}'"
wget "${URL}" -o "${FILE}"
done
I am trying to fetch the no. of rows for a particular ID using kubectl but instead getting some extra data.
Command:
kubectl exec abc-db-0 -n cicd --kubeconfig /root/admin.conf -- bash -c "psql -U postgres -d db -f /tmp/queryInstanceId.sql -v v1=full_test | grep [0-9]"
Actual Output of above command:
Defaulting container name to abc-db.
Use 'kubectl describe pod/abc-db-0 -n cicd' to see all of the containers in this pod.
(0 rows)
Expected Output:
(0 rows)
Could anyone please let me know what I am doing wrong here?
Note:
The first 2 lines always comes when we login to the DB manually but in output I only want (0 rows)
The first two lines are output by kubectl exec because the Pod has multiple containers. It is sort of a warning that it picked the first one, which might not be the one you wanted use.
You can specify the target container in your command (-c containername):
kubectl exec abc-db-0 -n cicd --kubeconfig /root/admin.conf -c abc-db -- bash -c "psql -U postgres -d db -f /tmp/queryInstanceId.sql -v v1=full_test | grep [0-9]"
Or you can redirect the standard error with kubectl ... 2>/dev/null (os specific):
kubectl exec abc-db-0 -n cicd --kubeconfig /root/admin.conf -c -- bash -c "psql -U postgres -d db -f /tmp/queryInstanceId.sql -v v1=full_test | grep [0-9]" 2>/dev/null

While loop stops reading after the first line in Bash

I thought that my problem is trivial, but I cannot figure out, why my scripts only performing once in array.
I have a jenkins job (bash script). This job gathering hostnames and sends ssh commands, through script, using gathered info:
rm /tmp/hosts
docker exec -t tmgnt_consul_1 consul members -status=alive | grep -v Node | awk '{print $1}' | cut -d : -f1 >> /tmp/hosts
sed -i '/someunnecessaryinfo/d' /tmp/hosts
echo >> /tmp/hosts
shopt -s lastpipe
while IFS= read -r line; do
echo "host is >>$line<<";
url="http://111.111.111.111:8500/v1/catalog/nodes"
term_IP=`curl -s $url | jq -r --arg Node "${line}" '.[] | select(.Node == "'${line}'" )|.Address' --raw-output`
echo $term_IP
sudo bash -x /home/rtm/t_mgnt/check_fw $term_IP
done < /tmp/hosts
Second script:
#!/bin/bash
term_IP=$1
sudo sshpass -p 'some.pass' ssh -o StrictHostKeyChecking=no user#$term_IP "sudo test -d /root/nv9"
if [ $? != 0 ]; then
sudo sshpass -p 'some.pass' \
scp -n -o StrictHostKeyChecking=no -r /home/rtm/t_mgnt/nv9 user#$term_IP:
sudo sshpass -p 'some.pass' \
ssh -n -o StrictHostKeyChecking=no user#$term_IP "sudo mv nv9 /root/"
sudo sshpass -p 'some.pass' \
ssh -n -o StrictHostKeyChecking=no user#$term_IP "sudo dpkg -i /root/nv9/libudev0_175-0ubuntu9_amd64.deb"
sudo sshpass -p 'some.pass' \
ssh -n -o StrictHostKeyChecking=no user#$term_IP "sudo /root/nv9/DetectValidator"
else
sudo sshpass -p 'some.pass' \
ssh -n -o StrictHostKeyChecking=no user#$term_IP "sudo /root/nv9/DetectValidator"
fi
The job is working fine, and returns correct values, but only for the first element of array.
PS - I already searched through this and other sites, and - following answer didn't help me - Shell script while read line loop stops after the first line (already "ssh -n -o").
Perhaps you can point me, what I missed.
Possibly this ssh call eats your input:
sudo sshpass -p 'some.pass' ssh -o StrictHostKeyChecking=no user#$term_IP "sudo test -d /root/nv9"

Try adding -n.
I'm trying to convert a hierarcy of TIFF image files into JPG, and out of boredom, I want to do find and ffmpeg in a single file.
So I set find to invoke sh with the -s flag, like thins:
#!/bin/sh
export IFS=""
find "$#" -iname 'PROC????.tif' -exec sh -s {} + << \EOF
for t ; do
ffmpeg -y -v quiet -i $t -c:v mjpeg ${t%.*}.jpg
rm $t
done
EOF
However, there's just too many files in the directory hierarchy, and find chopped filename array into several small pieces, and sh -s was only succesfully invoked for the first argument chunk.
The question being: how could one feed such in-body command to every sh invocation in the find command?
Update
The tag "heredoc" on the question is intended for receiving answers that do not rely on external file or self-referencing through $0. It is also intended that no filename would go through string-array processing such as padding with NUL-terminator or newline, and can be directly passed as arguments.
The heredoc is being used as the input to find. I think your best bet is to not use a heredoc at all, but just use a string:
#!/bin/sh
find "$#" -iname 'PROC????.tif' -exec sh -c '
for t ; do
ffmpeg -y -v quiet -i "$t" -c:v mjpeg "${t%.*}.jpg" &&
rm "$t"
done
' sh {} +
I am re-writing your code below:-
#!/bin/bash
find "$1" -name "PROC????.tif" > /tmp/imagefile_list.txt
while read filepath
do
path=${filepath%/*}
imgfile=${filepath##*/}
jpgFile=${imgfile%.*}.jpg
cd "$path"
ffmpeg -y -v quiet -i "$imgfile" -c:v mjpeg "$jpgFile"
rm -rf $imgfile
done < /tmp/imagefile_list.txt
IF you don't want to change the current directory you can do it like below:-
#!/bin/bash
find "$1" -name "PROC????.tif" > /tmp/imagefile_list.txt
# If you list down all the .tif file use below command
# find "$1" -name "*.tif" > /tmp/imagefile_list.txt
while read filepath
do
path=${filepath%/*}
imgfile=${filepath##*/}
jpgFile=$path${imgfile%.*}.jpg
ffmpeg -y -v quiet -i "$filepath" -c:v mjpeg "$jpgFile"
rm -rf $imgfile
done < /tmp/imagefile_list.txt
rm -rf /tmp/imagefile_list.txt
How i can parse the following function command line:
The separtor is (\s-\w\s) like -c or -d or -n
C:/my app/bin/Reader.dll -n Proc_20ms -c C:/Users/Braun/Desktop/test.csv -t Continue the simulation from the first line of the csv-file -j none -V errors and warnings (default) -d ,
to:
Match1: C:/my app/bin/Reader.dll
Match2: -n
Match3: Proc_20ms
Match4: -c
Match5: C:/Users/Braun/Desktop/test.csv
Match6: -t
Match7: Continue the simulation from the first line of the csv-file
Match8: -j
Match9: none
Match10: -V
Match11: errors and warnings (default)
Match12: -d
Match13: ,
Thanks.
Just put -\w inside a capturing group and then use this regex in re.split function. capturing group is necessary, so that it would keep the delimiter (ie, only the chars present inside the capturing group).
>>> s = 'C:/my app/bin/Reader.dll -n Proc_20ms -c C:/Users/Braun/Desktop/test.csv -t Continue the simulation from the first line of the csv-file -j none -V errors and warnings (default) -d ,'
>>> for i in re.split(r'\s(-\w)\s', s):
print(i)
C:/my app/bin/Reader.dll
-n
Proc_20ms
-c
C:/Users/Braun/Desktop/test.csv
-t
Continue the simulation from the first line of the csv-file
-j
none
-V
errors and warnings (default)
-d
