Hi,

I am reading a file (GC_JAR.log) which has entries like:

320325.566, 0.0453191 secs]

I want to replace all the entries of "secs]" with just "secs"

Thus, the output should be like:

320325.566, 0.0453191 secs


I tried using sed but it's not working for some reason.

# !/bin/bash
SRC=secs\[
TRG=secs
cat GC_JAR.log | while read line
do
echo "${line}" | sed 's/"${SRC}"/"${TRG}"/g' >> GC_cycles.csv
done


Any ideas?

Use of ' won't allow your variable to be expanded.
Use " instead and you can get rid of the inner ones.

whay that much scrpting req for that
use simple tr

tr '\]' ' ' <filename
sed 's/\]//g' filename
awk '/\]/{gsub("\]"," ")}{print}' filename

personally, i'd do it this way:

cat GC_JAR.log | sed 's/secs]$/secs/g'

I tested this on my own machine, and it worked like a dream:

rhobbs@mongoose:/tmp> cat deleteme.txt
320325.566, 0.0453191 secs]
320325.566, 0.0453191 secs]
320325.566, 0.0453191 secs]
320325.566, 0.0453191 secs]
320325.566, secs] 0.0453191 secs]
rhobbs@mongoose:/tmp> cat deleteme.txt | sed 's/secs]$/secs/g'
320325.566, 0.0453191 secs
320325.566, 0.0453191 secs
320325.566, 0.0453191 secs
320325.566, 0.0453191 secs
320325.566, secs] 0.0453191 secs
rhobbs@mongoose:/tmp>

Hope this helps!

Its not adviced to use cat command when you are using grep,sed or awk because they can take file as input...
so minimize the no of commands you use...

good point... i should have run sed 's/secs]$/secs/g' GC_JAR.log, of course!

I know it is a little late to respond. But just to make life easier for others who may come searching:
The above can be shortened a little by this:

sed 's/]$//' GC_JAR.log
