How can I list all existing workspaces in JupyterLab?
I know that one can view the current workspace name in the URL:
When you create a workspace, this creates a file in ~/.jupyter/lab/workspaces. The name of your workspace is in the ['metadata']['id'] key of the corresponding JSON file.
a simple code to list all workspaces is therefore:
import os, glob, json
for fname in glob.glob(os.path.join(os.environ['HOME'], ".jupyter/lab/workspaces/*")):
with open (fname, "r") as read_file:
print (json.load(read_file)['metadata']['id'])
For convenience, I created a gist with that bit of code. I have also added some cosmetics to directly generate the different URLs:
$ list_workspaces.py -u
http://10.164.5.234:8888/lab
http://10.164.5.234:8888/lab/workspaces/BBCP
http://10.164.5.234:8888/lab/workspaces/blog
I think you could try
ls ~/.jupyter/lab/workspaces
Each time u create a new workspace, there will be a corresponding file generated here. More detailed docs are here
As others have pointed out, workspace files are located at ~/.jupyter/lab/workspaces. Each workspace is represented by a .jupyterlab-workspace, which is actually just a JSON file.
If you have the CLI tool jq installed, the following one-liner gives you a quick list of workspaces:
cat ~/.jupyter/lab/workspaces/* | jq -r '.metadata.id'
Sample output:
/lab
/lab/workspaces/aaaaaaaaaaaa
/lab/workspaces/xxxxxxxxxx
With most basic shell commands:
grep metadata ~/.jupyter/lab/workspaces/* | sed -e 's/"/ /g' | awk '{print $(NF-1)}'
Output will look like:
/lab
/lab/workspaces/auto-x
/lab/workspaces/foo

I have two files. The first is a dnsmasq.leases file, text only. I can read this file using the -R switch. I have another file, macs.json, this file contains a json dictionary with mac address information in it. What I'd like to do is read these two files from jq cli using
jq -s raw:dnsmasq.leases macs.json
I can decompose it, and do it in stages, like:
jq -Rs '.|split("\n")' dnsmasq.leases | jq -s '.[0] as $macs|.[1] as $leases|etc' macs.json -
but I wondered if there was a way to read one raw and the other json at the same time?
You can always read a raw file using the --rawfile VAR FILENAME command-line option.
so I want to batch change name files with these type of names (about 400 files):
L1_Mviridis.fasta
L2_Mviridis.fasta
L3_Mviridis.fasta...
to this:
L1_1_Mviridis.fasta
L2_2_Mviridis.fasta
L3_3_Mviridis.fasta
I do not have the function "rename" available either.
Thanks for any suggestion!
you have two choices I suggest you can write a python script to rename each file first you split() function to split the underscore and extract the number the question is not that clear
Rename multiple files in a directory in Python
there is already an answer here also
Or you can use the mv command to rename mv <old name> <new name> and write a bash script to rename each one you can use sed or awk to rename each file
you can chain command for example ls -la | awk you can use for loop to iterate ls -l below is the guide to shell scripting

there is already an answer here
BASH: Rename multiple files. But only rename part of the filename
I hope this is a good starting point to you
With the conditions:
I cannot use any XML parser tool as I don't have permission , read only
My xmllint version does not support xpath, and I cannot update it , read only
I dont have xmlstarlet and cannot install it
I run my script using Java JSch exec channel ( I have to run it here )
So we have 3 files in a directory.
sample.xml
values1.properties
values2.properties
The contents of the files are as follows:
Sample.xml
<block>
<name>Bob</name>
<address>USA</address>
<email>$BOB_EMAIL</email>
<phone>1234567</phone>
</block>
<block>
<name>Peter</name>
<address>France</address>
<cell>123123123</cell>
<drinks>Coke</drinks>
<car>$PETER_CAR</car>
<bike>Mountain bike</bike>
</block>
<block>
<name>George</name>
<hobby>$GEORGE_HOBBY</hobby>
<phone>$GEORGE_PHONE</phone>
</block>
values1.properties
JOE_EMAIL=joe#google.com
BOB_EMAIL=bob#hotshot.com
JACK_EMAIL=jack#jill.com
MARY_EMAIL=mary#rose.com
PETER_EMAIL=qwert1#abc.com
GEORGE_PHONE=Samsung
values2.properties
JOE_CAR=Honda
DAISY_CAR=Toyota
PETER_CAR=Mazda
TOM_CAR=Audi
BOB_CAR=Ferrari
GEORGE_HOBBY=Tennis
I use this script to get the xml block to be converted to a properties file format
NAME="Bob"
sed -n '/name>'${NAME}'/,/<\/block>/s/.*<\(.*\)>\(.*\)<.*/\1=\2/p' sample.xml
OUTPUT:
name=Bob
address=USA
email=$BOB_EMAIL
phone=1234567
How do I get the value of $BOB_EMAIL in values1.properties and values2.properties. Assuming that I do not know where it is located between the two (or probably more) properties file. Bacause it should work differently if I entered
Name=Peter
in the script, it should get
name=Peter
address=France
cell=123123123
drinks=Coke
car=$PETER_CAR
bike=Mountain bike
and the think that will be searched will be PETER_CAR
EXPECTED OUTPUT (The user only needs to input 1 Name at a time and the output expected is one set of data in properties format with the $PLACEHOLDER replaced with the value from the properties file):
User Input: Name=Bob
name=Bob
address=USA
email=bob#hotshot.com
phone=1234567
User Input: Name=Peter
name=Peter
address=France
cell=123123123
drinks=Coke
car=Mazda
bike=Mountain bike
Ultimately, the script that I need has this logic:
for every word with $
in the result of sed -n '/name>'${name}'/,/<\/block>/s/.*<(.*)>(.*)<.*/\1=\2/p' sample.xml ,
it will search for the value of that word in all of the properties file in that directory(or specified properties files),
then replace the word with $ with the value found in the properties file
PARTIALLY WORKING ANSWER:
Walter A's answer is working in cmd line (putty) but not in Jsch exec.
I keep getting an error of No value found for token 'var' .
The solution beneath will look in the properties files a lot of times, so I think there is a faster solution for the problem.
The solution beneath will get you started and with small files you might be happy with it.
# Question has a bash en ksh tag, choose the shebang line you want
# Make sure it is the first line without space or ^M after it.
#!/bin/ksh
#!/bin/bash
# Remove next line (debugging) when all is working
# set -x
for name in Bob Peter; do
sed -n '/name>'${name}'/,/<\/block>/s/.*<\(.*\)>\(.*\)<.*/\1=\2/p' sample.xml |
while IFS="\$" read line var; do
if [ -n "${var}" ]; then
echo "${line}$(grep "^${var}=" values[12].properties | cut -d= -f2-)"
else
echo "${line}"
fi
done
echo
done
EDIT: Commented two possible shebang lines, set -x and added output.
Result:
name=Bob
address=USA
email=bob#hotshot.com
phone=1234567
name=Peter
address=France
cell=123123123
drinks=Coke
car=Mazda
bike=Mountain bike
. values1.properties
. values2.properties
sed -n '/name>'${NAME}'/,/<\/block>/s/.*<\(.*\)>\(.*\)<.*/echo \1="\2"/p' sample.xml >output
. output
Dangerous, and not the way I would prefer to do it.
A sed based version:
$ temp_properties=`mktemp`
$ NAME=Bob
$ sed '/./{s/^/s|$/;s/=/|/;s/$/|g/}' values*.properties > $temp_properties
$ sed -n '/name>'${NAME}'/,/<\/block>/s/.*<\(.*\)>\(.*\)<.*/\1=\2/p' sample.xml | sed -f $temp_properties
Gives:
name=Bob
address=USA
email=bob#hotshot.com
phone=1234567
It does have issues of script injection. However, if you trust the values*.properties files & contents of NAME variable, you are good to go.
I am trying to rename multiple files with extension xyz[n] to extension xyz
example :
mv *.xyz[1] to *.xyz
but the error is coming as - " *.xyz No such file or directory"
Don't know if mv can directly work using * but this would work
find ./ -name "*.xyz\[*\]" | while read line
do
mv "$line" ${line%.*}.xyz
done
Let's say we have some files as shown below.Now i want remove the part -(ab...) from those files.
> ls -1 foo*
foo-bar-(ab-4529111094).txt
foo-bar-foo-bar-(ab-189534).txt
foo-bar-foo-bar-bar-(ab-24937932201).txt
So the expected file names would be :
> ls -1 foo*
foo-bar-foo-bar-bar.txt
foo-bar-foo-bar.txt
foo-bar.txt
>
Below is a simple way to do it.
> ls -1 | nawk '/foo-bar-/{old=$0;gsub(/-\(.*\)/,"",$0);system("mv \""old"\" "$0)}'

Here is another way using the automated tools of StringSolver. Let us say your first file is named abc.xyz[1] a second named def.xyz[1] and a third named ghi.jpg (not the same extension as the previous two).
First, filter the files you want by giving examples (ok and notok are any words such that the first describes the accepted files):
filter abc.xyz[1] ok def.xyz[1] ok ghi.jpg notok
Then perform the move with the filter it created:
mv abc.xyz[1] abc.xyz
mv --filter --all
The second line generalizes the first transformation on all files ending with .xyz[1].
The last two lines can also be abbreviated in just one, which performs the moves and immediately generalizes it:
mv --filter --all abc.xyz[1] abc.xyz
DISCLAIMER: I am a co-author of this work for academic purposes. Other examples are available on youtube.
I think mv can't operate on multiple files directly without loop.
Use rename command instead. it uses regular expressions but easy to use once mastered and more powerful.
rename 's/^text-to-replace/new-text-you-want/' text-to-replace*
e.g to rename all .jar files in a directory to .jar_bak
rename 's/^jar/jar_bak/' jar*
Trying to rename a set of files in a directory with various filetypes, all with one common word, say 'foo', to another word, say 'bar' on a MacBook Pro.
E.g.:
foo.txt
form_foo.plist
home_foo.png
images_foo.zip
->
bar.txt
form_bar.plist
home_bar.png
images_bar.zip
Any ideas?
Use with care:
ls | grep foo | while read -r name; do echo mv "$name" "${name//foo/bar}"; done
That will report the commands it will run when you omit "echo". Inspect
the results, then rerun with "echo" omitted. This makes no attempt to work
on files with newlines in the name, nor does it recurse into subdirectories. If you want to work with files whose name begins with ., add -a to the invocation of ls. For safety's sake, you may want to add -i to the invocation of mv. Certainly make a backup first.
I don't have access to a Mac, but under Ubuntu you can use the rename command for this. Here's the man page in case that command is available
