sed with special characters
Hi,
I am reading a file (GC_JAR.log) which has entries like:
511725.629, 0.1122672 secs]
525268.975, 0.1240036 secs]
527181.835, 0.2068215 secs]
527914.287, 0.2884801 secs]
528457.134, 0.2548725 secs]
I want to replace all the entries of "secs]" with just "secs"
Thus, the output should be like:
511725.629, 0.1122672 secs
525268.975, 0.1240036 secs
527181.835, 0.2068215 secs
527914.287, 0.2884801 secs
528457.134, 0.2548725 secs
I tried using sed but it's not working for some reason. I read line by line from the original file ( GC_JAR.log ) and dump the final output in GC_cycles.csv
# !/bin/bash
SOURCE=secs\]
TARGET=secs
cat GC_JAR.log | while read line
do
echo "${line}" | sed 's/"${SOURCE}"/"${TARGET}"/g' >> GC_cycles.csv
done
Any ideas please? what's going wrong with sed command there.

drive.
The default action is to volcheck all checkable media managed by volume management.
OPTIONS
The following options are supported:
-i secs Set the frequency of device checking to secs seconds. The default is 2 seconds. The minimum frequency is 1 second.
-t secs Check the named device(s) for the next secs seconds. The maximum number of seconds allowed is 28800, which is 8 hours. The fre-
quency of checking is specified by -i. There is no default total time.
-v Verbose.

pathname The path name of a media device.
EXAMPLES
Example 1: A sample of the volcheck command.
The following example

asks Volume Management to examine the floppy drive for new media.

WARNINGS
Due to a hardware limitation in many floppy drives, the act of checking for media causes mechanical action in the floppy drive. Continu-
ous polling of the floppy drive will cause the drive to wear out. It is recommended that polling the drive only be performed during periods
of high use.
