why the case 2 will happen ? , ' should stop the history substitution ,shouldn't it?
No, it doesn't.
I find the ! history expanson annoying and intrusive; I always disable it in my .bashrc file with:
The exclamation mark is a printing character, and the ! key should print !.
zsh 4.3.4% cat file
ACFCFACCACARCSHFARCVJVASTVAJFTVAJVGHBAJ
zsh 4.3.4% cat file1
A
C
F
R
zsh 4.3.4% <file1 while read;do printf "%s=%d\n" "$REPLY" "${#$(<file)//}";done
A=9
C=7
F=4
R=2

MESSAGES(3) libbash messages Library Manual MESSAGES(3)NAME
messages -- libbash library that implements a set of functions to print standard status messages
SYNOPSIS
printOK [indent]
printFAIL [indent]
printNA [indent]
printATTN [indent]
printWAIT [indent]
DESCRIPTION
General
messages is a collection of functions to print standard status messages - those [ OK ] and [FAIL] messages you see during Linux boot process.
The function list:
printOK Prints a standard [ OK ] message (green)
printFAIL Prints a standard [FAIL] message (red)
printNA Prints a standard [ N/A] message (yellow)
printATTN Prints a standard [ATTN] message (yellow)
printWAIT Prints a standard [WAIT] message (yellow)
Detailed interface description follows.
indent
Column to move to before printing.
Default indent is calculated as TTY_WIDTH-10. If current tty width can not be determined (for example, in case of serial console), it
defaults to 80, so default indent is 80-10=10

printNA [indent]
