Shell Programming and Scripting

Hello All,

I have a file which contain data something like this:


CELL 2 TEST AND DIAGNOSTIC UNIT 2
CELL 2, CDM 1 CBR 1 TRANSMIT PORT (TXPORT) 1
CELL 2, CDM 1 CBR 2 TRANSMIT PORT (TXPORT) 1
CELL 2, CDM 1 CBR 3 TRANSMIT PORT (TXPORT) 1
CELL 2, CDM 1 CBR 1 TRANSMIT PORT (TXPORT) 2
CELL 2, CDM 1 CBR 2 TRANSMIT PORT (TXPORT) 2
CELL 2, CDM 1 CBR 3 TRANSMIT PORT (TXPORT) 2

CELL 3 PACKET PIPE (PP) 3
CELL 3, CDM 1 CBR 3 TRANSMIT PORT (TXPORT) 1

CELL 4 TIME FREQUENCY UNIT (TFU) 1
CELL 4 TEST AND DIAGNOSTIC UNIT 2
CELL 4, CDM 1 PRIMARY SIGNALING LINK
CELL 4, CDM 1 ALTERNATE SIGNALING LINK
CELL 4 PACKET PIPE (PP) 1
CELL 4 PACKET PIPE (PP) 2
CELL 4 PACKET PIPE (PP) 3

What i want is that i read that file and those lines which starts from cell 2 copies and paste into new file named cell2 in the same directory, same as for cell 2 and cell 3 and 4. Its mean that 3 new files will be created named cell2,cell3 & cell4.

Any idea how i can do this ??

cat cell | grep "CELL 2" > cell2
or
sed -n -e "/CELL 2/p" cell > cell2
or
awk '/CELL 2/{print $0}' cell > cell2

Hi,

the following script reads in the file line by line, then extracts
the filenumber from string, constructs the corresponding filename
and prints the matching information to this file. Blank lines are
delete.

Code:

while read line 
do 
[[ $line = *CELL* ]] \
&& FILENUMBER=$(sed 's/CELL \([0-9]\+\)[ ,].*/\1/' <<< $line) \
&& echo $line >> cell${FILENUMBER} 
done < file

Hello All,

I used this : cat cell | grep "CELL 2" > cell2 to read file named cell and to grep only lines that starts from cell 2. But when i open the output file cell2 so it also contain lines starting from cell 21 22 23 to 29.
But my requirement is that output file cell2 only contains lines that starts from cell 2 not from cell21 to 29.
I hope you understand what i am saying.

How i can do that?

Try this:

Code:

awk -F" |," 'NF{print > tolower($1$2)}' file

Use nawk or /usr/xpg4/bin/awk on Solaris.

Hi,

firstly: you don't need cat: grep "pattern" file is enough.
secondly: your regexp search for all patterns matching "CALL 2"
at "any position of any length".

Code:

grep "^CELL 2[ ,]" file

Will match only lines starting with "CELL" followed by "2" and a space
or comma.

Try my solutions. It should give you what you want. Save it in a
file a make it executable or run it from the command line.

Hello Christoph Spohr

Can you please tell me the usage procedure of your code:

Code:

while read line 
do 
[[ $line = *CELL* ]] \
&& FILENUMBER=$(sed 's/CELL \([0-9]\+\)[ ,].*/\1/' <<< $line) \
&& echo $line >> cell${FILENUMBER} 
done < file

where i have to put the filename which will be read.

i save your code and make it executable but its giving below error:
KarachiOMP root> ./co
./co: syntax error at line 6: `FILENUMBER=$' unexpected
