You can use sed :
sed -e 's/\([^\d]*\)/\L\1/' in.txt > out.txt
or perl inliner :
.
perl -ne 'utf8::decode $_; $_ = lc $_; utf8::encode $_; print' in.txt > out.txt
Both guys works fine for unicode file too.
Using telnet in bash scripts to automate some stuff ? It’s really easy, here’s an example to tell “hello world” on telnet server :
req="hello world"
server="my_server 1234"
val=`( echo open ${server}
sleep 3
echo "${req}"
sleep 1 ) | telnet`
echo $val
- Ubuntu doesn’t asking for login after boot up ( may happen after unexpected shutdown ) :
press Ctrl-Alt-F1 to login in terminal mode and use fsck to fix it - Add user short memo :
[root@my-box ~]# useradd -g users -u 560 tuser
[root@my-box ~]# passwd tuser
ps. sudo will be required in not-root case 🙂 - Proper access rights for .ssh files :
chmod 700 ~/.ssh
chmod 600 ~/.ssh/id_rsa
chmod 644 ~/.ssh/id_rsa.pub
chmod 644 ~/.ssh/authorized_keys
chmod 644 ~/.ssh/known_hosts
- List all files in folder sorted by size :
find . -type f -exec du -k "{}" \; | sort -n
Microsoft is offering about 20,000 lines of its own device drivers to the Linux kernel that will enable Linux to run as a guest on its Hyper-V virtualization technology. Specifically, the contributed loadable kernel modules enable Linux to run in ‘enlightened mode’, giving it efficiencies equivalent to a Windows virtual machine running on Hyper-V.
