Shell Programming and Scripting

i hav a text file(abc.txt) in which it have 2 lines as shown

Number of agencies didnt send the file= 0

sum of reject files= 0


######
to get one line from the text file ... i use grep command
grep 'Number of agencies didnt send the file= 0' abc.txt

but for both the lines ..... what i want to use.......

can any one suggest

try:

Code:

egrep 'Number of agencies didnt send the file= 0|sum of reject files= 0' abc.txt

Code:

awk '/Number of agencies didnt send the file= 0/||/sum of reject files= 0/' abc.txt

@rdcwayx
@anchal khare

its not working
can u plz solve it..... its showing not found....
but the lines are in the file

From what I can see, Anchal Khare has a good solution. Read the grep/egrep/fgrep manual pages. The command given is saying:-

Code:

Get "first bit of text I'm searching for" or "second bit of text I'm searching for" from file abc.txt

The command egrep (or grep -E on AIX) allows you so speficy an extended regular expression as the search criteria, so you can set up both phrases.

Perhaps you could shrink the search to just

Code:

grep "=" abc.txt

.... unless that generates lots of wrong hits. It should find every line containing the equasl sign.

It's difficult to tell with such limited input how to neatly phrase the expression.


I cannot really comment on the awk solution because I'm not very practised.


I hope that this helps

i have a text file abc.txt as shown below
##################### text file begins####################
MONTH_20100801_1_IN.txt 2310 1042 0
MONTH_20100803_1_IN.txt 0708 708 0
MONTH_20100804_1_IN.txt 023 023 0
Number of agencies didnt send the file=0
sum of reject files= 0
MONTH_20100802_1.txt
MONTH_20100802_1_IN.txt
MONTH_20100805_1_IN.TXT
####################### end #########################
i need to run a script based on the values of those 2 lines
Number of agencies didnt send the file=0
sum of reject files= 0
if they both are zero i hav to run a script

######### for only one statement ...i wrote
grep 'Number of agencies didnt send the file=0' abc.txt
RC=$?
if [$RC -ne 0]
####some message
else
#### run script
fi
################################
i wann to worte like this if both the statements are zero....

One way is to use egrep and count the results.
The escaped $ (\$) means "end of line" in case the program outputs numbers above zero with leading zeros.

Code:

found_count=`egrep "Number of agencies didnt send the file=0\$|sum of reject files= 0\$" myfile.txt | wc -l`
#
if [ ${found_count} -eq 2 ]
then
        echo "Run my script"
fi

Note in your example data there are subtle differences in spacing near the equals signs. The "egrep" reacts to the exact spacing.
