[Oh My Zsh] Would you like to check for updates?
Type Y to update oh-my-zsh: y
/home/user/.oh-my-zsh/tools/upgrade.sh: 2: Bad substitution
Simply do :
cd ~/.oh-my-zsh
git pull
And everything should be OK!
Everyday is the same thing... how could I be efficient without unix tools... Here are some examples that save my life everyday (ok, not everyday, but at leat one time a week...). The objective is to manipulate a text file, sort lines, find and extract duplicates lines.
The example is based on a very simple data file, but it works the same way with something more complicated… ;-)
So let’s begin with the data file (file to work on). Note that “0000″ is visible twice :
cat data.txt
0000
1111
4444
2222
0000
Now let’s sort the lines :
cat data.txt | sort
0000
0000
1111
2222
4444
Now let’s find unique lines :
cat data.txt | sort | uniq
0000
1111
2222
4444
Now let’s find duplicates lines :
cat data.txt | sort | uniq -d
0000
