I want to generate ssh public key using ssh-keygen with custom host name in it at the end of the file
.
How to change the host name locally in bash.
Just provide the -C flag, the stuff at the end of the file is only a comment, not used for anything else except differentiation.
ssh-keygen -C "somecomment#somehostname"
The hostname at the end of the key file (id_rsa.pub) is just a comment. You can change is with any editor.
or if you really want to do it from the command line:
awk '{$3 = "myname#myhost.com"; print;}' id_rsa.pub > new_id_rsa.pub

How can I change the 127.0.0.1 to another IP address using echo or cat without nano or Vim?
Here's the Bash command and the Bash file name is listpics:
python3 poc.py --cmd listPics --ip 127.0.0.1
For your specific case, you could do this:
with open('listpics', 'r+') as listpics:
data = listpics.read().replace('127.0.0.1', '192.168.1.254')
listpics.seek(0)
listpics.write(data)
listpics.truncate()

I'm working a shell script to admin out email system. Essentially I get the users info and grep it to get the data I need. I've ran the below commands in terminal and they work as intended but when I use the below script I get an error "Command not found". I think its trying to run the 3rd line as a command. Anyone know what could be the problem here?
read -p "Enter email address to remove from groups: " purge_email
purge=$(python /gam/gam.py info user $purge_email)
purge_chunk=$($purge | grep -A 100 "Groups:")
echo $purge_chunk
Try:
purge_chunk=$("$purge" | grep -A 100 Groups:)
the $purge should be evaluated as formatted output the way gam kicks it out in a txt file or .csv you would use as a data source for a gam script in bash.

the name.sh already save in C:\Documents and Settings\user, i type sh name.sh
sh: testing.sh: No such file or directory
any help will be appreciated!
You can just type ./name.sh and your script should run.
If your current directory is not in your $PATH, adding the ./ tells the shell to look there.
The other possibility is that you're not currently in the right directory. If the result of pwd shows you are not in C:\Documents and Settings\user, then you will need to cd to that directory, or move the script to whatever directory you are in.
Add ./ in front of the name. ./name.sh
