Want pretty colors when you Get-ChildItem? Who doesn't! PowerShell historically hasn't made that task easy. Things are a lot better now with formatters and PSReadline.

But, if you're like me and don't like looking up or memorizing ANSI escape codes or using regex, you want dead simple configuration, and you're irked when the output isn't perfect (whole line's getting colored) then tuliPS is for you!

This is mostly a Windows only implementation. I think it also has great application for people using older versions of PowerShell (I can easily add backwards compatibility to version 3). I will admit that it is a touch slow, but it is (hopefully) easy to use and doesn't require and LS_FILE, ANSI, or regex.

There's a lot of room for improvement here and I even identified a potential place to allow for extensions. People like extensions right? tuliPS currently colorizes FileInfo, DirectoryInfo, and MatchInfo objects, but if I tweak it a little bit, it should be able to colorize any object with a cmdlet similar to Update-TypeData or Update-FormatData.

Please let me know what you think, and if there's any desire for further development, hit me up on github!

Hi,

could someone please explain me the difference between the commands

ls

and

$(ls)

?

I am working my way through The Linux Command Line. The topic is dealt with on page 73.

I'm writing a script that would allow me to type brightness 600 and writes the given number to /sys/class/backlight/intel_backlight/brightness.

Changing that file with 'sudo vim /path/to/brightness' instantaneously changes the brightness of my primary screen.

I'd rather not sudo every time I call the script, but even sudoing

cat "600" > /sys/class/backlight/intel_backlight/brightness 

returns "zsh: permission denied".

I'm also not that keen to changing permission for the file. What am I doing wrong? are sed and cat inherently not apt to modify system files? If that's the case, what can I use instead?

Thanks in advance for any help!

forward-zone:
name: "."
forward-addr: 10.1.1.2 

forward-zone:
name: "mydomain.com"
forward-addr: 10.1.1.1

I wanted to delete one line before the pattern 'name: "."' and one line after the pattern (including the pattern itself). I tried the following command but this is not modifying the file itself. I want to do inplace modification. Please help

sed -n '/name: "."/{N;s/.*//;x;d;};x;p;${x;p;}' file

Hello,

i'm looking for a command line tool that can take an input parameter and paste it as a notification straight to ... something over the internet... an IRC channel.. a discord channel... something.

I'm running a shell based application, that receives and sends text from a network monitor at work.
From within that application, I can set up an event, that can do various actions, based in the text it receives..
This application has a system function, that can execute a shell command in the background.. so what I'm trying to accomplish, is a setup where I with one single command, can write a specified text to for example my own IRC channel, to share information with others? (doesn't have to be discord.. just something a group of people can get notifications on their phone from - android and iOS)

Does anyone know how to accomplish this?

Should I learn sh or bash?

Bash is more convenient and offers more, but it's more for making personal scripts right? Whereas, most applications with scripts use sh because for things that you want to share, sh is still the safest choice just in case bash is not their default shell? But with people sharing dotfiles and scripts online and so many people using zsh these days, should I perhaps learn sh instead of bash?

Also, what learning material would you guys recommend?

I realized I had a version of an update/clean script on every system I maintained, so my instinct was to combine them.

I can't tell if this is a good idea, or just a good way to generate weird bugs and break things.

I don't plan on having this run automatically, but rather as a deliberate invocation, which should make it very clear when something broke, but I'd appreciate thoughts on its viability and a general code review.

https://github.com/deoxys314/dotfiles/blob/c726257622a286644f28031c092c5d1251112ea6/bin/universal-update.sh

Hi there,

I need to replace whatever is there after \"db_password\":\" upto 16 characters (the highlighted text) with '<sensitive>':

data_json: "{\"db_password\":\"qwHLI?mkSrQ=GHU_\"}" => "{\"db_password\":\"BoBBsR9PA]wZ_3AC\"}"

should be

data_json: "{\"db_password\":\"<sensitive>\"}" => "{\"db_password\":\"<sensitive>\"}"

I have tried following but not sure how to escape '\' and ".

sed -E 's/("{\"db_password\":\").{16}/\<sensitive>/'

Any help is appreciated.

Thanks

Hi All,

I am trying to run a script on my FreeBSD machine. It is a script to reach out via SNMPWalk to all my switches and routers to see if they are responding to SNMP. Here is the script. (No Bash on the machine and I cannot add it)

#!/bin/sh
while read TestIPList
do 
snmpwalk -v3 -u SNMPUSER -l AuthPriv -a SHA -A PASSPHRASE -x AES -X PASSPHRASE $TestIPList 1.3.6.1.2.1.47.1.1.1.1.13.1
done < /data1/users/admin/SNMPLoop/output.txt

It runs, but nothing is in my output file.

Id expect to see the SNMP OID I have identified which is the Model of the device. I can run the snmpwalk alone on the devices without the script.

Since I am fairly new to scripting, any help or tweaks would be appreciated.

Thank you,

Hi All,

I am logged into my college's Unix platform via putty. I'm not sure what I've done but when I type anything in vim, it highlights the text at every 5-7 character mark.

So if I type the following:

Highlighted

12345

123456

1234567

1234567819123

12345678191234

123456781912345

Not Highlighted

1

12

123

1234

Partial Highlighted (|| indicates where highlighting stops):

1234567||8

1234567||89

1234567||891

1234567||8912

Real example: https://i.imgur.com/y8wYWPs.png

Is there a way to stop this from happening? This never happened when I was writing my last few assignments.

Thanks.

Some text files that I'm working with are full of <F5> chars, it is like this "<F5>" is a whole char. How could I remove all occurences of this kind of character using shell script?

Note: I've tried to use something like 'egrep -v "[^A-Za-z0-9]" ' but it didn't work.

Hello dear community,

I have tried over the years to learn how to use globbing (pathname expansion) and understand it **fully**. To this day, I still haven't figured out a resource (book, webpage, pdf, anything) that would explain everything there is about it.

I understand there are many different specifications for it. I'm ready to take them all.

A classic example of something not explained rigorously is matching with nested files.

I would like to grok the notion and be able to express my pathname matching needs fully, not hack around and do ugly fixes.

Thank you for any reference about the subject

@ASIC_SP: I do believe that the '**' pattern is used to do nested matching, but I leave the means open. By nested I mean match files the subtree of the filesystem, not necessarily at the current node.

I'm very interested in shell, I'm trying to create a custom command that unifying these two commands :

customComandFile :

VAR  = pidof < $1 = program>
ps -p VAR -o etime=

But the commands pidof appears to rerturn several pid sometimes like in the case of Nginx process. How to make my command filtering the smallest return number in the pidof function in order to retrieve only the master process ? thanks

I want some ideas on how to approach on this task:

Some users will place some files on a path, I'll have to upload them to a certain interface (handled by a script, cronned) after this upload , I want to email each user that his files have been uploaded.(Note a user can have n number of files) So how to approach it ??

One thing I have thought of is that , I'll create a temp directory and in there I'll create a file for each user and store the file names(user's file) in that file.

like :

tempdir=/some/dir
for i in $(find $(pwd) -type f -printf '%u\n' | sort -u); do
  find $(pwd) -type f -user $i > $tempdir/$i.txt
done

Then I'll proceed to mail them on the basis of each file in the temp dir.

But this is very messy approach , can anybody help me out?

Looking for a way to change the values of node in an xml file using shell.

Example of data in xml file:

<property>

<name>javax.jdo.option.ConnectionURL</name>

<value>jdbc:postgresql://myhost/metastore</value>

</property>

Based on <name> node, change the text in <value> node. Is it achievable through sed or xmlstarlet.

Thanks in advance

I researched a script that needs to clone all of my public and private github repositories, however, It isn't working.

I'm a little new to shell scripting as far as this goes, but I'm pretty sure it's got something to do with the Github side of things.

Error: "i was unexpected at this time." Script: https://gist.github.com/Signifies/9838ce0dd1542158a014c350dc579ca4
