How to echo Brackets from a file
I'm a beginner of c shell scripting.
How I can echo a whole line from a file with bracket in it?
Ex. Inside the file.txt
abcd [5:0] efghi

This is what inside the c shell

Code:
set IN_FILE = file.txt
set GREP_KEY = 'abcd'
set IN_LINE = `grep ${GREP_KEY} ${IN_FILE}`
echo $IN_LINE

After excuting, the whole line containing 'abcd' won't display then I tried to remove the bracket from the file and it works.

Thank you.

Don't use C shell for scripting, if for anything. With a standard shell, that would be:
Code:
#!/bin/ksh
IN_FILE=file.txt
GREP_KEY=abcd
IN_LINE=$(grep $GREP_KEY $IN_FILE)
echo $IN_LINE

Maybe (- no C shell here ...):

Code:
echo "$IN_LINE"

I'm trying to copy a line of a file with brackects in it and store the line temporarily in the variable and output it to a new file, and below that line I will write a new line before the second line of the old file is being written to the new file.

Old file:
Code:
0001 REG1 [7:0] Register 1
0002 REG2 [7:0] Register 2
0003 REG3 [7:0] Regsiter 3

New file: (expected output)
Code:
REG1 [7:0] Register 1
REGW 0001 1234
REG2 [7:0] Register 2
REGW 0002 5678
REG3 [7:0] Regsiter 3
REGW 0003 9ABC



REG1,REG2 and REG3 are the patterns I whish to GREP from the old file.
Thanks

try:

Code:
set IN_FILE = file.txt
set GREP_KEY = 'abcd'
set IN_LINE = "`grep ${GREP_KEY} ${IN_FILE}`"
echo "$IN_LINE"

Again: Don't use C shell for scripting, it's a waste of time.
