I am trying to search string and replace string in a file. I used the below code:
sed -e 's/{"AP_SESSION_ID"\1\"787"}/{"AP_SESSION_ID"\1\"800"}/g' FILE|tee FILE
but it is not working and the output is like this:
sed: number in \[0-9] invalid
My environment is CYGWIN.
sample file is:
DP_SESSION_ID is a sting for values
DP_SESSION_ID is aplicat
"DP_S42SETTACC_TYPE"\1\"02"
"DP_SAP_CLIENT"\1\"460"
"DP_SAP_COMM_CONNECTION"\1\"JAVA_COMM_TOOL_ANALYZER"
"DP_SAP_CONNECTION"\1\"JAVA_TOOL_ANALYZER"
"DP_SAP_TOOLBI_CONNECTION"\1\"JAVA_TOOLBI_ANALYZER"
"DP_SESSION_ID"\1\"808"
I want search this "DP_SESSION_ID"\1\" sting and replace corresponding number like 808 in file prenatally(windows env), and i wand sing line command in windows bat command or perl command i don't want scrip or program
even i have installed cygwin tool in my server so unix also ok but single line command
server: windows 2008,cygwin x
using tool : datastage server jobs
perl -pi -e 's{" "DP_SESSION_ID"\1\"808 '"}{' "DP_SESSION_ID"\1\"900 '"'"}g' " file name
this code is not working
Please give good solution
You need to "escape" the backslashes by using two in a row:
sed -e 's/{"AP_SESSION_ID"\\1\\"787"}/{"AP_SESSION_ID"\\1\\"800"}/g' FILE|tee FILE
Otherwise the \1 is treated as a backreference, and you have no subgroups (parenthesized expressions) to reference.
