Bash tips

# bash history without numbers
history | cut -c 8-
history | cut -d' ' -f4- | sed 's/^ \(.*$\)/\1/g'

SED

# Insert string to configuration file
# To append after the pattern: (-i is for inplace replace). line1 and line2 are the lines you want to append(or prepend):
 
sed -i '/pattern/a \
line1 \
line2' inputfile
 
# To prepend the lines before:
 
sed -i '/pattern/i \
line1 \
line2' inputfile
 
# Find all SSL CA activators and change string from apache to apache2
find /home/broot/ -name "*SSL_CA_activator.sh" -type f -exec sed -i 's/\/apache\//\/apache2\//g' {} ";" -exec sed -i 's/\\\/apache\\\//\\\/apache2\\\//g' {} ";" -exec sed -i 's/\/etc\/rc.d\/apache restart/\/etc\/rc.d\/apache2 restart/g' {} ";"
 
# Finding with DSSH
dssh "find /home/broot/ -name \"*SSL_CA_activator.sh\" -type f -exec ls -la {} \";\"" | less
 
# Path correction in httpd.conf file
dssh "sed -i \"s/\/usr\/local\/apache2\/icons/\/usr\/local\/apache2\/share\/icons/g\" /usr/local/apache2/conf/httpd.conf"
 
# Find and replace
find -type f -exec sed -i 's/OLD-STRING/NEW-STRING/g' {} \;
