I have to change the title of a couple of hundred files by adding the vdate from its header to its title.
If vdate = 19971222, then I want the name of that nc file to become rerun4_spindown_19971222.nc
I know I can find the vdate by ncdump -h filename (see example header below).
ncdump -h rerun4_1997_spindown_09191414_co2
netcdf rerun4_1997_spindown_09191414_co2 {
dimensions:
lon = 768 ;
lat = 384 ;
nhgl = 192 ;
nlevp1 = 96 ;
spc = 32896 ;
// global attributes:
:file_type = "Restart history file" ;
:source_type = "IEEE" ;
:history = "" ;
:user = " Linda" ;
:created = " Date - 20190919 Time - 134447" ;
:label_1 = " Atmospheric model " ;
:label_2 = " Library 23-Feb-2012" ;
:label_3 = " Lin & Rood ADVECTION is default" ;
:label_4 = " Modified physics" ;
:label_5 = " Modified radiation" ;
:label_6 = " Date - 20190919 Time - 134447" ;
:label_7 = " Linda " ;
:label_8 = " Linux " ;
:fdate = 19950110 ;
:ftime = 0 ;
:vdate = 19971222 ;
:vtime = 235800 ;
:nstep = 776158 ;
:timestep = 120. ;
However, then I have to manually open all the files and manually change the title of the file... of hundreds of files. I would prefer making a bash that can automatically do that.
I am sure there must be a more intelligent way to extract the vdate from the nc header, could you guys help me out?
Thank you!
In theory, something like that should work:
#! /bin/sh
for file in rerun4_*_spindown_* ; do
vdate=$(ncdump -h $file | awk '$1 == ":vdate" { print $3 }')
new_name="rerun4_spindown_$vdate.nc"
mv "$file" "$new_name"
done
I do not have access to netCDF files - more testing is needed.
When I have my global git hooks directory (which contains just a prepare-commit-msg hook) set up in config, my local commit-msg doesn't run (although the global hook does). However, when I disable the global prepare-commit-msg hook (by commenting out core.hookspath in gitconfig), the local commit-msg hook works just fine.

Edit: As #phd pointed out in the comments, "The problem is that global hookspath completely takes over local hooks. If the global hookspath is defined local hooks are never consulted. [I had] to create global /Users/shreyasminocha/dotfiles/git-hooks/commit-msg that [would] run local .git/hooks/commit-msg". Confirming duplicate.
Eventually solved this by adding some code to the global hook, just as #phd suggested. It looks for a local hook and runs it if it exists.
Global prepare-commit-msg hook:

Oh... String interpolation, once again... Replace this line
#o = 'curl #{dns_name}' with:
#o = "curl #{dns_name}"
I explained why it was the problem below.
You can see from editor that end is not recognised. Maybe you copy/pasted some code before and some characters (like quotation marks) are not the same format as your editor uses. So rewriting this short peace of code might save your ###. And paste whats rewritten here :)
elsif writes as a single word, but Ruby probably understands it, since no error I got using it this way..
String interpolation is used with double quotes
'curl -s #{dns}'
Supposed to be:
"curl -s #{dns}"
(Expect you really want to output this as "curl -s #{dns}")
Was the problem one of these?
I just pasted this into repl.it and it works well. Please check if it meets your code (I have added a value to dns_name variable since I do not have it defined in my case):
dns_name = 10
10.times do
# visit load balancer

o = "curl -s #{dns_name}"

I'm making a script that reads a tracking code, looks at the results of posting the tracking to a website and prints some messages and has a return value.
Here's part of the python code:
# update return True if there was a change to the .msg file
def update(cod):
msg = extract_msg(cod)
if msg == 'ERROR':
print('ERROR: invalid code\n')
sys.exit(2)
file = open('.msg', "r+")
old_msg = file.read()
if msg == old_msg:
return False
else:
print('Previous message: ' + old_msg)
print('Latest message: ' + msg)
file = overwrite(file, msg)
file.close()
return True
def main(argv):
if len(argv) > 1:
cod_rastr = argv[1]
else:
print("Error: no arg, no code\n")
return -1
# Verify if file exists
if os.path.isfile(".msg") == False:
arq = open('.msg', 'w')
arq.close()
# post() returns the source code of the resulting page of the posted code.
cod = post(cod_rastr)
if update(cod) == False:
return 0
else:
print ('\n Message!\n')
return 1
And here, I want to read not only the prints (for the final user) but the return values (for conditional use). This script should read the output of the .py and send me an email in case there is an update from the last check (I'll put this script in the crontab):
#!/bin/bash
if [ -z "$1" ]; then
echo usage: $0 CODE
exit
fi
CODE=$1
STATUS=$(myscript.py $CODE 2>&1)
VAL=$?
FILE=$(<.msg)
# always prints 0 (zero)
echo $VAL
# I want to check for an existing update case
if [[ $STATUS == 'Message!' ]]
then
echo $STATUS
echo $FILE | mail myuser#mydomain.com -s '$CODE: Tracking status'
fi
The problem is that $? always returns 0, and my string check inside the if, is not working, because I think It reads the update() prints too, which has variables in the print.
How can I make this shell script run, without changing the python script?
Thanks in advance.
I suspect that you can do what you want with the subprocess module. Either use rc = subprocess.call(...) to get a return code while directing stdout to a file, or use p = subprocess.Popen(...) and then perhaps p.communicate to get output and p.returncode to get the returncode.
Xcode allows you to create automated scripts for performing repetitive tasks. What scripts have you written to speed up development?
I've created three for my JSON.Framework for Cocoa and the iPhone. These take care of the following:
Creates a release Disk Image with dynamic embedded Framework, custom iPhone SDK, API documentation and some documentation files in.
Run Doxygen over the source to create an Xcode-compatible documentation set and install this. This means when you search for things in Xcode's documentation search your documentation can be found too.
Run Doxygen over the source to update a checked-in version of the API documentation in the source tree itself. This is pretty neat if you use Subversion (which it assumes) as the documentation is always up-to-date for the branch you're in. Great if you're hosting on Google Code, for example.
Beware some hard-coded project-specific values in the below. I didn't want to potentially break the scripts by editing those out. These are launched from a Custom Script Phase in Xcode. You can see how they're integrated in the Xcode project for the project linked above.

This is an improvement of the "Create Property and Synths for instance variables" script that Lawrence Johnston posted above.
Settings:
Input: Entire Document
Directory: Home Directory
Output: Discard Output
Errors: Ignore Errors (or Alert if you want to see them)
Select any number of variables and it'll create properties and syns for all of them. It'll even create/edit your dalloc method as necessary.
Edit up the results if they are not exactly right (copy vs. retain, etc.)
Handles more things like underbar storage name, behavior, dealloc,…

Here's one that I found somewhere else that creates #property (copy) and #synthesize property directives for an instance variable. It could use a bit of improvement (say, to let you synthesize multiple variables at once), but it's better than creating them by hand.
Select the instance variable you want to create a property for and activate the script.
If I want a (retain) instead of (copy) I just activate the script and change it to retain manually (it's smart enough to not include the (copy) on primitive types such as int to begin with).
