Putty screen freeze due to CTRL + S.
"Every
time I accidentally press Ctrl + S in Putty when connected to any Solaris box
via SSH, my session stops responding. How do I restore it?"
The reason:
Apparently
CTRL+S actually does XOFF, which means the terminal will accept key strokes but
won’t show the output of anything. It will appear as if your terminal is dead
when it’s really just waiting to be turned back on. The fix? Simply press CTRL+Q
to turn flow-control on (XON).
Important Note: All / Any keys you hit after hitting ctrl +
s will be Buffered and Sent when you hit ctrl + q.
Warning: Don't send harmful commands. Because if you
hit ENTER, it gets buffered too. All those commands WILL BE SENT and EXECUTED.
View the Control Characters in a file.
To find out the control characters in a file :
# cat -vet filename
-v
Non-printing characters (with the exception of
tabs, new-lines and form-feeds) are printed visibly. ASCII control
characters (octal 000 - 037) are
printed as ^n, where n is the corresponding ASCII character in the
range octal 100 - 137 (@, A, B, C,. . ., X, Y, Z, [, \, ], ^, and _); the DEL
character
(octal
0177) is printed ^?. Other non-printable characters are printed as M-x, where x
is the ASCII character specified by the low-order seven bits.
-e
A $ character will be printed at the end of each line (prior
to the new-line).
-t
Tabs will be printed as ^I's and formfeeds to be printed as
^L's.
return to previous directory
for Linux if u
want to return to previous directory you can type.
$ cd -
this also works for Solaris, but if not working u can try this.
$ cd ~-
it's depends on your shell...

awk ..
If you have a server with a lot of file systems on it. Then
this little “awk” command can come in useful. It can obviously be used in many
other situations also.
In this example, the disk group name is /homedg/.
bash-3.00$ grep homedg /etc/vfstab
/dev/vx/dsk/homedg/sanlogs
/dev/vx/rdsk/homedg/sanlogs /var/log/sanlogs
vxfs 1
yes -
/dev/vx/dsk/homedg/common
/dev/vx/rdsk/homedg/common /usr/local/common
vxfs 2
yes -
bash-3.00$
bash-3.00$ awk '/homedg/{print "mount -F
"$4,$1,$3}' /etc/vfstab
mount -F vxfs /dev/vx/dsk/homedg/sanlogs /var/log/sanlogs
mount -F vxfs /dev/vx/dsk/homedg/common /usr/local/common
bash-3.00$
If you run it with piping it to 'sh', then it will execute
the command. You can replace the 'mount' with whatever command you like.
