First post, so I hope someone can help me with this weirdness
I have a number files with some rows of information I want to extract, at the same time I want to add to a string some details from the file. I have found two different ways of looping over rows in a file, but one method doesn't let me concatenarte strings and I don't know why....
The first method sets the IFS environmental variable. I don't really favour this method, but it works..
Code:
#!/bin/bash -
OLDIFS=$IFS
IFS='
'
STE="cat"
for FILE in $( ls *-df | cut -f 4 -d / ); do
N=0
for LINE in $( cat $FILE ); do
N=$((N+1))
STE="$STE""dog"
done
done
echo "$STE" && exit
and produces:
catdogdogdogdogdogdogdogdogdogdogdogdogdogdogdogdo gdogdogdogdogdogdogdogdogdogdogdogdog
Method 2 uses "read" but prevents the concatenation of the string:
Code:
#!/bin/bash -
STE="cat"
for FILE in $( ls *-df | cut -f 4 -d / ); do
N=0
cat "$FILE" | while read LINE ; do
N=$((N+1))
STE="$STE""dog"
done
done
echo "$STE" && exit
and produces:
cat
Why is there a difference in the two methods? I would rather not be changing environmental variables and a simple loop is my preferred choice.
Thanks for your help, as this has been driving me crazy...

Hi there,
I'm writing a basic script where I want to make a string of 2 numeric fields from a file, which I have done, but the behavior is rather confusing.
I have a file of random values such as:
1 2
3 4
5 6
7 8
9 10
and my awk code is:
BEGIN { FS = " " }
{ str = str $1 $2 }
END {... (7 Replies)
Hello
I want to achieve the following.
However the concatenation is not working
mv `ls -ltr *myfile*.log|awk '{print $9}'` `ls -ltr *myfile*.log|awk '{print `date +'%d%m%y%k%M%S'` $9}'`
I tried
awk '{x=`date +'%d%m%y%k%M%S'` print $x "" $9}'

What i want to do is to... (8 Replies)
