My useful Linux commands

Some Linux commands I find useful:

Replace a string in all files recursively usind sed ( replaces repository.jboss.com with anonsvn.jboss.org/repos/repository.jboss.org)

grep -rl repository.jboss.com . | xargs sed -i 's/repository.jboss.com/anonsvn.jboss.org\/repos\/repository.jboss.org/'

/usr/share/applications

uname -r

Find string "proxy" in all files
sudo find . -type f -name "*" -exec grep -l "proxy" {} \;

find . -name "*" -exec grep "proxy" {} \;      (donne tous les lignes avec Test_1)

find . -name "*" -exec grep -l "proxy" {} \ ; (donne tous les fichiers avec Test)

grep -r 'proxy' *
