Top Forums Shell Programming and Scripting Notify as soon as an error is encountered in a script Post 302984243 by mbak on Sunday 23rd of October 2016 03:03:34 AM

My apologies for missing out a value in the script, it should have been as below,

Code:
if grep -w $DISK1 NEWDISK.list | read  VG DISK2 DISK3

Since I'm replacing multiple disks, I want to get an email or I can set it up to send an alert whenever the "replacepv" command fails for any reason like disk not found or something before trying to run "replacepv" on next disk in sequence in other words notify me as soon as it fails at any point during the script execution. I noticed that ERR.OUT doesn't log anything if I use a disk that doesn't exist which throws an error on screen.

set_color(1)							       fish							      set_color(1)

NAME
set_color - set_color - set the terminal color set_color - set the terminal color Synopsis set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR] Description Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple, cyan, white and normal. o -b, --background Set the background color o -c, --print-colors Prints a list of all valid color names o -h, --help Display help message and exit o -o, --bold Set bold or extra bright mode o -u, --underline Set underlined mode o -v, --version Display version and exit Calling set_color normal will set the terminal color to whatever is the default color of the terminal. Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey font color, while set_color --bold white will result in a white font color. Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator. set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of ncurses and recompile fish against it in order to fix this issue. Version 1.23.1 Sun Jan 8 2012 set_color(1)
