I need to create a script that inserts the echo command at the beginning of each line of the file and at the end > > blocodenotas, for example

#!/bin/bash
ls -l
uname -a
netstat -tunap

I want a script that turns this into:

echo "#!/bin/bash >> log"
echo "ls -l" >> log"
echo "uname -a" >> log" 
echo "netstat -tunap >> log"

script bash shell shell-script

You can use the awk utility to solve your problem with just one line, see:

$ awk '{ print "echo \"" $0 "\" >> log"  }' script.sh > saida.txt

With thirst it is also possible:

sed -i -e 's/^/echo \"/;s/$/ >> log\"/'  arquivo
