Hi all,

Below is a script to parse IOS crash logs. What I wanted to do, was take in the file process the command, then replace the lines that have our appname in them. Currently the output, looks identical to the original file. I think the sed line is the issue (woof=`echo $tempFile | sed `$cmd``). Any help would be greatly appreciated. Banging my head against the desk at the moment.



#! /bin/bash
APPNAME=$1
FILENAME=$2
BUGNAME=$3
echo APPNAME IS $APPNAME
echo FILENAME IS $FILENAME
contentsOfFile=`cat $FILENAME`
tempfile=$contentsOfFile
echo $tempfile
for i in `grep -n $APPNAME $FILENAME | grep [1-9]* | awk '{print $1 "," $2 "," $3 "," $4 "," $5 "," $6}'`
do
myline=$i
linenumber=`echo $myline | cut -d':' -f 1`
echo linenumber: $linenumber
hexaddr=`echo $myline | cut -d',' -f 3`
echo $hexaddr
if [[ -n "$hexaddr" ]]
then
atosResult=$(atos -arch armv7 -o $APPNAME".app/$APPNAME" $hexaddr)
else
hexaddr=0x00000
#atosResult=$(atos -arch armv7 -o $APPNAME".app/$APPNAME" $hexaddr)
fi
sedCommand=$linenumber's'
echo $sedCommand
echo Atos command before sed: $atosResult
atosResult=`echo $atosResult | sed "s/'//"`
echo Atos command after sed: $atosResult
cmd="$sedCommand/.*/$atosResult/"
echo CMD:$cmd
woof=`echo $tempFile | sed `$cmd``
echo Woof: $woof
done
for f in "${tempfile[@]}"
do
echo "Processing $f file..."
echo >>"$OUTPUT"

while IFS='' read -r line; do
printf "%s\n" "$line">>"$OUTPUT"
done <"$f"
echo >>"$OUTPUT"
echo >>"$OUTPUT"
done
echo "$tempfile" > $BUGNAME


Edited: It seems to be a problem with the atos command and what it returns. This has [ brackets - dashes and * in the text. See my post below for an example. I need a way to in line of text replace a line with the atos result. Thanks all.

That said line that you pointed out is most likely not being parsed properly, due to the back ticks. I would try to set a new variable as the output of $cmd, and then set "woof" as $(echo $tempFile | sed $cmd_var) or something of that nature. Also, try to use $() instead of backticks, as using backticks is older practice.

Try also adding set -xv to the start of the script (ie after shebang) and view what is happening as each line is processed.

Hi All,

I think it has to do with the output of the atos command. It has several spaces and crazy characters. For instance
'+[OFASIHTTPRequest runRequests] (in ourgame) (OFASIHTTPRequest.m:4501)' When sed runs against this it either gives invalid command code or runs out of
"181s/.+/+[OFASIHTTPRequest": unterminated substitute in regular expression <---that warning. How can I pass the sed to have it ignore those characters? Keep in mind every line will be dynamic in how it comes from atos and each line of code. Thanks all in advance.

Hi.

Try to put $cmd into double quotes (instead of backticks), like this
Also make sure $atosResult does not contains slashes.
